Corset Onesie - Deep Navy


Size Guide
This product is SOLD OUT!

Inspired by Regencycore, the Corset Onesie is the head-turning staple your workout wardrobe has been waiting for.. 

This figure-accentuating one-piece features princess seams at the bust that extend into the leg for an all-around, fit-like-a-glove feel. We love this onesie for its feminine keyhole cutout which allows this unitard to move + support your body like a second skin. This head-turner is complete with satin adjustable crisscross straps, and faux-corset detail at the waist for the ultimate waist-cinching illusion. 

Bonus: Have a long torso? The keyhole detail provides you with extra stretch, conforming to your body’s natural shape. This opening allows for universal fit flexibility.

I was a onesie nay sayer before this item dropped. I'd tried the runsie which just didn't work for me and I almost gave up but the navy and coreset detail just called to me. I am so glad I gave it a chance! It is so cute and the fabric is super soft. I've worn it to the gym and for a day out and it's been perfect for both occasions.

About the sizing, I am S top (33.5 inches) and M bottom (39 inches) so I sized up and I am not sure that was the right call. The fact that the straps are adjustable (thank god!) saved this outfit for me but the top is a bit less secure than is ideal for me. Meanwhile the bottom is very comfortable and stretchy so I think having tried a small would have worked better. If this ever comes out in another color I think I might try and size down. And if you do make more, pockets please!

Not quite there

Onesies/rompers never work for me but I was really excited to try this because it’s supposed to be long-torso friendly. It looks really cute, but unfortunately it’s still not long enough. I have to tighten the straps to get the bra part to sit where it should be, which makes them dig into my shoulders. If I loosen them to a comfortable length then my boobs look saggy. I wish they would make separates because I love the lace up corset detail. My torso is ~63-64” while the model my height and size has a torso length of 58. I would definitely recommend measuring your torso before ordering!

My new favorite outfit

This has become one of my favs. It doesn't feel too tight, probably could have gone down a size, but since I am a bit hippie, went up a size just in case. The girls seem supported, but I wouldn't do a workout where you are jumping around as they may pop out. The only thing bad is that when I was putting it on the first time, the stitching in the back where the waist is came apart a little. Other than that I love it. Do wish it had a pocket for your phone

I'm in love

This is brilliant, I'm short with big boobs and bum and this fits without fabric folds or pinching, and it's so soft

It's not quite supporting enough to do anything to energetic without a little extra support underneath, but for low impact it's great
