I teach pilates many times during the week and it's so breathable yet thin enough to feel like it's not see through. A lot of clients ask if it's worth the price and I always say yes!

Recently lost over 50 pounds and decided to look into new workout clothes. I came across 437 through a content creator on tiktok and was instantly influenced. I went ahead and purchased the onesie not knowing that my obsession would begin. I absolutely love this onesie and looking forward to purchasing more of their items!

I love!! would definitely recommend
Jocelyn A. 5/5 Verified
I think it’s a very flattering onesie! Definitely better for not so taxing or sweaty workouts. I’m a 34 DD and it doesn’t offer much, if any, support, so big chests bear that in mind. I’m 5’4, 140 lbs, in shape and a M was perfect. I love my 437 stuff! I personally just need more support and wish there was a built in bra in this one.

I had my eye on the onsie for a bit and finally decided to buy it after I fell in love with Reformer Pilates. Honestly, I don't know why I waited so long. As someone who's still trying to adjust to their body after having a baby three years ago I love the onsie as nothing rolls up or down (like wearing a separates) allowing me to move confidently when I focus more on the moves and enjoying the class instead of a bought of insecurity. My only complaint is that I'm really between a large and xl and I opted for the xl because I find the large in their activewear is just a smdige to small, so it fits a little bit looser in some parts but not by much.

I love every piece from 437! From the onesies to the bike shorts and sports bras I get so many compliments at the gym and the material is such good quality. I am 5’7 and wear an X Small in most of the activewear and its super stretchy and comfortable.
