Corset Onesie - Deep Navy


Size Guide

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.

Fit Stylist Tips and Try-On Girls Feedback

Hi all, Jules, your POPFLEX Fit Stylist is coming at you with an honest review compiled by our Try-On girls.

Special shout-out to Annie, Erinn, Lindsey, and Victoria for their help.

Pros: This onesie is a fantastic fit flexible piece because of the center cut-out and adjustable straps it works for all heights you can see the girls range from 5’1 to 5’10! Speaking of the center cut-out, It helps keep you cool on the hot girl summer walks because it is added ventilation. The drawstring detailing adds interest and a fashionable spin on the bodice, reviewers reported the elevated style made them feel like they could go from the gym to errands feeling pulled together and cute. The feel and function of the fabric made the corset onesie a favorite of one reviewer who said… “ I feel so snatched in this and the fabric is buttery soft like a dream.”

Cons: Reviewers with larger cup sizes did report they would need to layer a bra under to provide support for any activities that have more than light impact. One reviewer noted, “ The straps are thin and can easily twist, but once they are in place they stay put, and it was nice to be able to adjust the straps.”

So cute!

Very happy with the quality and cuteness of this onesie! All the little details make it extra cute and my partner complimented how good it looked on me immediately so that's always a win! Very comfortable to wear and work out in. Only downside is that because of the front center seam there is a definite camel toe. I also found that the bust area tends to slip down a little but maybe I just have't found the right strap length yet and it should be tighter than I would normally go, I have a small bust though so for a larger bust it seems something to note. Overall though very happy with it and would definitely consider buying another style.

I received so many compliments on it. Have always been self conscious and this makes me feel powerful. It’s very soft, has a unique design, and is comfortable.

Perfectly uplifting

My mom suddenly died 2 weeks ago, and I ordered this onesie hoping that a cute workout outfit would get me out of the (can’t eat sleep get out of bed)rut. I put it on as soon as it arrived. It supported my bust a (38E). It’s adorable, versatile, and most of all it allowed me to see the progress I’ve made with my body, which then motivated me to get back on the mat for myself, and I killed that workout.

A Great Surprise

I honestly wasn't sure I would like this. I'm glad I gave it a shot though. I love it! The fabric choice is super soft and the color is amazing. The top fits very nicely. Adjustable straps are a great feature. I agree we other reviews, pockets would be a game changer. Regardless, I love this outfit. Great addition to the collection!
