Product Insights

It stays in place without rolling down, features a double-gusset for easy bathroom access and no underwear needed, but runs small despite sizing charts and requires hand washing and flat drying to maintain compression.

Smoothing your silhouette under dresses and outfits
This sculpting open-bust bodysuit is designed with front and side panels to smooth the silhouette and flatten the tummy, with a smooth finish under clothing and mid-thigh hems that lie flat. One shopper reports it smooths lumps and bumps very well, while noting it's not a glamorous piece to wear.[1,2,3,4]
Shapewear for a booty-enhancing look
The Spanx Oncore Open-Bust Mid-Thigh Bodysuit has pockets at the back designed to enhance the booty. Wear it under outfits when you want a smooth, lifted look from your torso through your thighs.[3]
A one-piece option when shapewear shorts roll down
One Reddit commenter says she hates how shapewear shorts roll down no matter the brand or cut, and she uses this Spanx Oncore Open-Bust Mid-Thigh Bodysuit instead. She reports it smooths lumps and bumps very well, though she does not say outright whether it stays put. She adds it is not the most attractive piece in her drawer.[2]
Product comparison
Compared within this brand.
| Oncore Open-Bust Mid-Thigh Bodysuit Length: 6": Choose this if you want an open-bust, mid-thigh bodysuit with a 6-inch inseam, bonded tummy panels designed for maximum sculpting and core control, and front and side panels meant to smooth your silhouette under clothing. It offers adjustable back straps, molded underwire-style bra cups, booty-enhancing back pockets, a 100% cotton gusset, and an ultra-soft 80% nylon, 20% elastane microfibre in black (small and large). One wearer reports it smooths lumps and bumps very well, though she also calls it the least sexy thing in the world, so it suits function-focused shoppers more than lingerie appeal.[1,2,3,4] | Spanxsculpttm Gofigure Bodysuit Length: 6": Choose this if you want firm high-compression shaping in a thin, open-bust bodysuit: Spanx says its SPANXsculpt and printed LYCRA FitSense zones deliver powerful control with a lighter, second-skin feel and breathability, and one wearer found it comfy despite the compression. The seamless construction, bonded edges, and scooped back are designed to disappear under fitted clothing, with mid-thigh 6-inch legs, an inseam gusset opening, adjustable thin straps, and a stomach-flattening OnCore panel. Note that your bra is worn underneath but sold separately, and the shaped, defined look is per the brand's own description.[5,6,7,8,9] | Suit Your Fancy Plunge Bodysuit 7" Length: Choose this if you want sculpting shapewear that stays hidden under deep-plunge necklines and low backs: it has a U-shaped plunge front, a patent-pending adjustable low back, and 5-way convertible straps (traditional, criss-cross, halter, narrow back, or racerback), plus molded cups and a 7-inch mid-thigh inseam. The body is an ultra-soft nylon-blend microfibre (51% elastane, 49% nylon) with a three-hook back closure, adjustable back straps, and an inseam gusset opening. It comes in Black (sizes SMALL to X-LARGE) and Beige (SMALL to LARGE), so the Beige option is limited if you need a larger size.[10,11,12,13,14] |

Different expectation
Seemed to be of good quality, as in everything was in its place. Can smooth some edges. But returned it as I was expecting something more powerful.

User recommends Spanx Oncore Open-Bust Mid-Thigh Bodysuit for smoothing
I HATE the roll down of the shorts and seems it happens no matter what brand/cut/whatever. I use this one: https://www.spanx.com/shapewear/bodysuits/oncore-open-bust-mid-thigh-bodysuit. It’s the least sexy thing in the world but it really smooths the lumps and bumps super well!!
