Finally filled out my shirts
I'm pretty slim and most of my shirts just hang off me. This gives them some shape without me buying a whole new closet.
Jake M.
★★★★★
Less obvious than I expected
Thought the padding would scream fake. Under my regular button-down, it just looks like I have a little more chest and shoulders.
Brandon T.
★★★★★
Kept checking the mirror
Put it on before dinner and actually liked how my outfit looked from the side. That almost never happens.
Ryan H.
★★★★★
The arms make a difference
Everyone talks about the chest, but the sleeves were the thing for me. My polo doesn't look empty around my upper arms anymore.
Tyler W.
★★★★★
Still looks like me
I wasn't trying to look like a bodybuilder. Just wanted to look a little less narrow in pictures. This is more my speed.
Chris B.
★★★★☆
Small packaging gripe
Four stars because the bag was pretty plain. The shirt itself looked good under my outfit, so that's honestly my only nitpick.
Nathan C.
★★★★★
Tried it sitting down too
Standing in front of a mirror is one thing. I sat down, reached for stuff, moved around. Didn't spend dinner adjusting my shirt.
Matt S.
★★★★★
Better from the back
My shoulders usually look narrow from behind. With this under a shirt, the shape across my upper back looks way better.
Andrew P.
★★★★★
Glad I could adjust it
Took out a couple of pads until it looked right with the shirt I was wearing. I like having that choice.
Kevin R.
★★★★★
Bought it for one wedding
Had a wedding coming up and hated how my dress shirt fit. Wore this underneath and stopped messing with my jacket all night.
Josh D.
★★★★★
Didn't need a tighter shirt
I kept buying smaller shirts to get some shape, then the collar would be too tight. This worked with the size I already wear.
Austin K.
★★★★★
The white one worked for me
Wore it under a fairly thick white dress shirt. Looked clean. I'd still check it in daylight with whatever shirt you're planning to wear.
Eric L.
★★★★★
My shoulders finally show up
I have a decent jacket but always felt lost in it. The extra shape at the shoulders made the whole outfit look more put together.
Justin A.
★★★★★
Didn't go overboard
Left some of the pads out for a more subtle look. That's the version I keep reaching for.
Dylan F.
★★★★★
Way better in a polo
Tried it with my navy polo first. More shape across the chest and arms, without changing my whole style.
Zach G.
★★★★★
Less second-guessing
Usually change shirts three times before going out. Put this on, picked one, left the house. Nice change for me.
Sean V.
★★★★★
Not just a front view thing
Checked the side and back because that's where I thought it would look weird. My regular shirt sat pretty naturally over it.
Alex N.
★★★★★
A little boost
I go to the gym. I'm just not very big yet. This helps my clothes fit better in the meantime.
Cody J.
★★★★☆
Wish the bag was reusable
Giving it four because I'd have liked a nicer bag to keep it in. Happy with how it looks under my shirts though.
Ben O.
★★★★★
Not a costume
That was my main worry. With the pads adjusted and a normal shirt over it, I just looked like a fuller version of myself.
Adam E.
★★★★★
Date-night shirt is back
Had a shirt I loved the color of but never wore because it looked flat on me. Actually wore it out last weekend.
Luke I.
★★★★★
Stayed put during dinner
Was expecting to keep fixing the pads. For a normal evening sitting, walking, and eating, I left it alone.
Daniel Q.
★★★★★
The V shape is the point
For me it's the shoulders and upper back together. My shirt looks broader up top instead of straight down.
Michael U.
★★★★★
Start with your own clothes
Tried a few shirts I already owned before deciding how much padding to keep. My usual button-down was the winner.
Connor Y.
★★★★★
Useful for photos
I normally turn sideways or hide behind someone in group pictures. Felt fine just standing there this time.
Nick Z.
★★★★★
Liked the black one
Under my darker shirts, the black version is the one I use most. Gives me the shape I wanted without being the focus of the outfit.
Jason M.
★★★★★
Worth trying different setups
At first I used every pad. Then I took a couple out and liked it more. Glad it wasn't all or nothing.
Ethan B.
★★★★★
Didn't feel ridiculous
Felt a little silly ordering this, honestly. Then I tried my shirt over it and got why people would want one.
Travis S.
★★★★★
My sleeves sit better
My upper arms are pretty lean. The extra shape under the sleeves made my short-sleeve shirt look less baggy.
Derek T.
★★★★★
No wardrobe overhaul
Same pants, same shoes, same shirt. Just liked the way it all looked on me more.
Steven H.
★★★★★
A better side profile
My chest normally disappears under a dress shirt. This added enough shape that I noticed it from the side too.
Brian W.
★★★★☆
Would like another color
Four stars because I'd use a gray one too if there were one. Nothing wrong with the black one I got; I just like options.
Kyle P.
★★★★★
Not every shirt needs every pad
I use a little less padding with my fitted shirts. More with the roomier ones. Pretty simple once I tried a few outfits.
Aaron D.
★★★★★
Felt good at the party
Nobody gave me some big movie moment. I just felt better in my clothes and wasn't thinking about my skinny shoulders all night.
Patrick R.
★★★★★
Checked it in normal light
Tried it by the window, not just in the bathroom mirror. With my usual shirt on, the shape looked pretty natural.
Scott C.
★★★★★
Better under a jacket
My blazer had always looked a bit empty through the chest. This filled it out enough that I actually wanted to wear it.
Jeremy K.
★★★★★
You can dial it back
Wasn't after a huge change. Took out what I didn't need and kept the shoulders and chest the way I liked them.
Logan F.
★★★★★
Less boxy from behind
The upper-back shape was a surprise. My shirt looked less like a rectangle from the back.
Trevor L.
★★★★★
A confidence thing for me
I'm not pretending it changed my actual body. I just like how I look dressed with it on, and that was the whole point.
Grant A.
★★★★★
Kept my normal style
Didn't have to start wearing super tight stuff. It looked good under the kind of shirts I already like.
Owen N.
★★★★★
More than just the chest
The shoulders, arms, and back all make a difference together. It doesn't just push out the front of my shirt.
Blake E.
★★★★★
Tried it before the event
Did a full outfit check at home first. Glad I did, because a different shirt looked better with it. Happy with the final outfit.
Colin J.
★★★★★
My usual tee looked different
Tried it under a heavier T-shirt rather than a dress shirt. The shoulders and sleeves were what stood out to me.
Jordan V.
★★★★★
Didn't need the biggest look
The biggest setup wasn't for me. A smaller amount of padding gave me the extra shape I was after.
Wesley G.
★★★★☆
One tiny presentation thing
Four stars because the packaging wasn't really gift-worthy. Bought it for myself, so it barely mattered. Liked the fit under my shirt.
Brad R.
★★★★★
Less pulling at my clothes
I usually keep tugging my shirt forward because I hate how flat it sits. Didn't catch myself doing that nearly as much.
Caleb D.
★★★★★
Good for the outfit I had in mind
Wanted it for a fitted button-down and dark pants. Tried that exact outfit and it gave me the look I was hoping for.
Hunter P.
★★★★★
Didn't have to keep it a big deal
I put it on like another layer and got dressed. After a while I was more focused on the night than on how my shirt looked.
Dean S.
★★★★★
Nice to have the choice
I don't wear it with everything. But for the shirts where I want a little more shape, it's nice to have it there.
Cole B.
★★★★★
Still my clothes, just better
The best part wasn't looking massive. It was putting on clothes I already owned and finally liking the way they sat on me.

Will It Show Under My Clothes?
FORMHOM is designed to give you a fuller, more athletic silhouette underneath your clothes. Its low neckline helps keep the undershirt out of sight.
For the most natural finish, wear it under a shirt or T-shirt with enough room to sit smoothly over the padding. Visibility depends on the fabric, color and fit of your outer layer.
Materials & Comfort
An acrylic and LYCRA blend gives FORMHOM a flexible, close-fitting base that stretches with your movements.
The fabric follows your shape, while the built-in padding adds definition to your upper body. Designed to sit beneath your outfit, with a low neckline for easy layering.
How Does It Work?
How Does It Work?
Put it on, add your shirt, and see the difference. Built-in padding adds visible volume to your chest, shoulders, arms and lats for a broader upper body and a more defined V-shaped silhouette.
Your shape, your way. Removable pads let you adjust the added volume to suit your outfit and the look you want.
The effect is visual while you wear it; it does not change your body or build muscle.

needed some new pics for my Tinder profile and randomly decided to buy this for them. honestly didn’t expect much, but the photos came out so good 😂
now I end up wearing it pretty often when I go out. it’s actually insane how much better clothes fit with it on.
Gave it the ultimate test with a really tight stretch shirt and it looked amazing. You genuinely couldn’t tell I had anything underneath.
I love it. I’ve already ordered two more, one in white and one in black.
my son bought one a couple of months ago. I stole it from him one Saturday night… then did it again 😂
In the end he gave me a 2-pack so I’d stop taking his. Honestly still cracks me up.
la llevé puesta en una boda prácticamente 24 horas seguidas y, sinceramente, se me olvidó por completo que la llevaba. Cuando llegué a casa y empecé a desnudarme para irme a dormir pensé: “ostia, si todavía llevo esto puesto” 😂
Creo que eso dice más sobre lo cómoda que es que cualquier otra cosa
honestly, I wasn’t expecting much when I ordered it. I thought it would just be another random thing I’d try once and never use again.
Then I put it on and I was genuinely shocked. I asked my roommate if he could tell I was wearing anything underneath and he literally couldnt believe it when I showed him. The difference it makes is crazy.
I originally bought it for a costume party because I was dressing up as Spider-Man and wanted the suit to actually fit and look right.
I honestly thought I’d only use it once, but now I wear it pretty much every weekend when I go out with my friends. It makes such a difference to how my clothes fit that it ended up becoming part of my normal going-out outfit.
Creo que la gente debería mirar esto de otra manera. Las mujeres llevan años utilizando cosas para realzar su apariencia — maquillaje, pestañas, sujetadores con relleno, fajas, tacones, extensiones de pelo, lo que quieras — y está completamente normalizado.
A veces todo eso puede cambiar bastante su apariencia y nadie lo ve como un problema. Así que no entiendo por qué debería verse diferente que un hombre lleve algo debajo de la ropa para hacer que su outfit le siente mejor.
No cambia quién eres. Simplemente hace que la ropa te quede mejor y que tu aspecto general se vea más favorecido. Precisamente por eso yo me la pongo siempre que me arreglo para salir.
We seriously need to get over this idea that there’s something wrong with wanting to look better. Women wear makeup, false lashes, padded bras, shapewear, heels, fake nails… and nobody thinks twice about it.
I see this exactly the same way. It’s just part of the outfit, not part of who you are. I wear mine pretty much every time I dress up to go out now. It just makes everything I wear look better.
I honestly expected it to feel uncomfortable, but not at all. After wearing it for a while, you barely even notice it’s there. It just feels like you’re wearing your shirt or sweater normally.
It took a little longer than expected to arrive because they ran out of stock, but it was definitely worth the wait. The quality is really good, and once you put it on, it’s completely unnoticeable under your clothes.
Nunca lograba esa silueta en v por mi genética, pero funciona genial para rellenar esas zonas problemáticas. Recibo cumplidos constantes sobre mi silueta.
Having a flat chest made me avoid certain outfits and it's a very practical and discreet solution. My posture looks better and my clothes drape perfectly.
Shopping for clothes always ended in disappointment and it transforms your build in literally two seconds. I finally have the presence i wanted in a suit.
even tailored shirts didnt give me the presence i wanted. the way it fills out the chest and arms is amazing, so i can wear lighter clothes in summer without anxiety.
Me frustraba mucho ver que las camisetas me quedaban flojas. Con este producto la caída de la ropa cambia por completo, así que recibo cumplidos constantes sobre mi silueta.
Sentía que me faltaba presencia al ponerme un traje y no da nada de calor extra y el resultado es brutal Es un alivio no pensar en mis hombros todo el rato
Las camisas de mi talla me qdaban grandes de hombros, pero añade la forma exacta q necesito para q la ropa asiente. La tranquilidad de saber q te ves bien no tiene precio.
I hated seeing how frail i looked in group photos. This shirt acts like a foundation for my outfits. I don't worry about my narrow frame at work anymore.
Custom suits were too expensive and still didn't add bulk, but this creates a visual illusion that works flawlessly I finally have the presence i wanted in a suit
La ropa entallada me hacía parecer más delgado aún y funciona genial para rellenar esas zonas problemáticas, así que ahora por fin me veo bien con mis camisas favoritas.
Finding clothes that fit my slim build was a nightmare, but it's a very practical and discreet solution My posture looks better and my clothes drape perfectly
Tener los hombros caídos arruinaba mi forma de vestir. El efecto que consigue en el pecho es muy realista, así que el cambio de actitud que te da esto es impagable.
Odiaba cómo me quedaban los trajes en las bodas. Funciona genial para rellenar esas zonas problemáticas, así que la tranquilidad de saber que te ves bien no tiene precio.
Every time i looked in the mirror wearing a shirt it looked shapeless, but i slip this on underneath and it looks natural, so i don't have to overthink my outfits anymore.
I was sick of feeling like a teenager in adult clothing. It structures my upper body perfectly. People have noticed i look better but can't pinpoint why.
Being a skinny guy means nothing ever drapes properly. The extra bulk is distributed exactly where it should be, so i don't worry about my narrow frame at work anymore.
My posture is fine but my frame is just naturally thin, but putting this on completely changes my silhouette, so people have noticed i look better but can't pinpoint why.
Siempre he tenido complejo por tener el pecho plano. Al ser transpirable la uso a diario sin ningún problema, así q ya no tengo q preocuparme de parecer frágil.
