SLEEK AND MINIMAL

A sculpting silhouette designed to flatter from every angle. The Halter Onesie features a clean halter neckline with an empire seam that defines the waist, paired with a sleek open back for a modern, confident look. A minimalist underbust strap offers secure support, while the capri-length leg with subtle flare elongates the body. Finished with an invisible scrunch for a lifted effect, and crafted from moisture-wicking recycled fabric for all-day wear.

The jumpsuit is so flattering! I’m 5’4” and ordered my usual size, and it fit perfectly. I have a smaller chest, so the low-cut neckline was just right, and it still felt very secure during workouts.

Customer photo review of The Halter Onesie / Cream

I loved this cream onesie. The material is great. The halter doesn’t bother me really the only part is the side void part is a little big. For my boobs on the side but it is also possible i should have gotten one size smaller but my top is smaller than my hips. either way I'm ordering again and i keep getting compliments!

Gorgeous silhouette!!! Such a cute and sexy piece! Had to get both colors. Love the buttery soft material! So flattering and true to size! Only downside is the halter does hurt my neck by the end of the day.

Its not made for bigger chested women, my boobs were falling out the sides. Also, its see through in the white color. Just didnt feel like it was worth the price.

Maranda J. 2/5 Verified

Love it, only 4 stars mainly because its not so much tall girl friendly, originally ordered a large but needed to exchange for the XL because the large didnt have a long enough torso for me. Im 5’7 for reference.
