I ordered this for my daughter. That's what she wanted. She loves it. The quality the finish, the fact that it's a zip at the front and not on the side. It's a perfect fit. She loves it that much. She's going to order up another one

Honestly the best binder I’ve tried, comfortable and easy to breathe in, only note is that the fit at the bottom was quite loose. It looks fine under clothes, it just feels a little weird. Aside from that though, 10/10! :D

Better
I bought the mesh binder and used Wonababis size guide and was a 4XL but had to order a 3XL, it was way too large and didn't bind at all so I ordered this one in a L and low and behold it fits and binds. I'd probably go with a XL next time but if you're getting one of these binders have a bit of money before you do as you might need to order a few times to find your actual size... also, it's a racer back which personally I absolutely hate as it reminds me of sports bras. If they did a full back of this binder it would get a 5 star but just for the racer back I'm knocking one off. Other than that, not a bad binder, I could recommend it for those with disabilities as the zip makes it so much easier to get on and off. Sensory wise the material is great but if you're like me and hate racer backs you'll loathe it. I'll update my review in a few months once I've worn it in.

Brilliant at binding the body and building confidence
My 12yr old loves this so much this is the 2nd one I bought. She is in the early stages of exploring who she is and said it is comfortable and makes her flat in the right places. Makes the male clothes I have bought look better and makes her feel more confident in her body. She has breaks during the day using it and takes it off after school or her breast do hurt. But when it's on they are flattened well. We are now looking for more underwear that is masculine for ftm as male boxers are too baggy at the front.

Incorrect size and broken upon receiving
Ordered it, checked the size, even bought a more expensive so I knew there would be good quality, when it showed up the zipper was snapped and it was 2 sizes too small.

Bad size charts order t shirt size instead
I looked verry closley at the sizeing charts and mesured myself and it reccomended that i get a size 4xl because of my mesurments but i know these things run large so to be safe i got a 2xl, when it came it was HUGE on me (im 5’1 70kg with E cups so thats sayin alot) pay no attention to thier sizing charts if you want something that works just order whatever shirt size you wear maby one up if you want it looser, will be reordering in a large good quality just bad sizing

Meu peitoral é 82 cm, a baixo dele é 75 cm e escolhi P (S) mesmo o recomendado sendo um número maior. Ficou apertado pra colocar e não consigo colocar sozinho por enquanto (até afrouxar), mas acho que ficou o mais justo/apertado/comprimido que poderia ficar, não me arrependo de ter pego o tamanho P/S. Fiquei satisfeito com o resultado Sempre usei fichário, é a minha primeira vez usando de zíper e definitivamente prefiro zíper agora

Ich dachte es wäre einer der typischen, günstigeren Binders. ABER - dieser hier hat mich für Preis-Leistung überzeugt. Er macht seinen Job gut, zumindest beim ersten Eindruck. Wirklich getragen habe ich ihn noch nicht. Aber fühlt sich sehr gut auf der Haut an, bindet wirklich gut und ich liebe das Rückenteil, denn das ist ein Unterschied zu den sonst sehr breiten Stoffrücken. Definitiv eine Kauf-Empfehlung!

J'ai acheté ce corset pour moi , mais ça taille vraiment petit , ça ne doit pas être une taille européenne mais plutôt asiatique et pourtant j'ai pris la plus grosse taille . Sinon c'est de la bonne qualité, le tissu est respirant, léger, la fermeture éclair monte et descend sans dérailler. La couleur chair est plutôt discrète. Conclusion, je pense que lorsqu'on à une forte poitrine, c'est un modèle pas adapté point de vue taille , sinon je recommande

This is my first binder and I was a little afraid at first to put it on. After hearing all the things that could go wrong from binding, like trouble breathing, how could I not be at least the tiniest bit nervous? But after wearing it to work for a week, I work in a factory, I was surprised by how comfortable it was and that I had no issues breathing in it. I am 5'6 with a bit of a chubby build and DDs, so I got a 2XL and it fit perfectly. The compression feels really good and made my chest flat enough to look like pecs, as long as I pulled the tatas to the side, and the spandex in the back had the right amount of stretch to give ample mobility. The quality of the fabric and zipper is really good. However, the printed tag on the inside rubbed of after a few days of wearing it. I don't blame the company for that, I blame the amount I sweat while I am at work XD. The only issue I have is that the bottom rolls up when I sit down, but that might just happen because of my chubby tummy and my bad posture. Wearing a thin tanktop or spaghetti strap under it kind of helps with that issue. Overall, the best first binder to get for the price and it does exactly what it is supposed to while making you look good.
