Selene Thong – Shaping Bodysuit

The Selene Thong shaping bodysuit combines tummy and waist shaping, back smoothing and a U-shaped bust design that supports and lifts the bust from underneath. Its medium-firm compression defines the waist and creates a more pronounced hourglass effect, helping fitted outfits sit more smoothly on the body.

Inspired by waist-training corset construction, the X-shaped compression structure targets the tummy and waist, while the double-layer tummy panel creates a smoother, more defined midsection. Added support across the back helps create a cleaner, more streamlined silhouette under clothing.

One of Selene’s key features is its U Push-Up bust design. The open-bust shape frames and supports the bust from below to create a more lifted-looking décolletage. Because the bust remains open, you can also pair the bodysuit with your own bra and choose the support and shape that works best for your outfit.

The thong back provides minimal coverage, helping reduce visible underwear lines under fitted clothing. This makes Selene an especially practical foundation under bodycon dresses, skirts and tailored trousers.

If you choose just one shaping bodysuit, make it the Selene.

Of course, this is subjective, but the Undershape team is unanimous: Selene is our favorite shaping bodysuit in the entire collection. We simply love it because it creates a beautifully sculpted silhouette while remaining comfortable enough to wear all day.

It provides firm shaping around the tummy and waist, supports and smooths the body beautifully, and enhances your natural, feminine curves. Whether worn under a dress, trousers, or a more elegant outfit, it’s the kind of essential you’ll reach for again and again.

Thong or classic brief version, our answer is the same: if there’s room for only one bodysuit in your wardrobe, Selene is the one we’d choose.

Its soft, flexible and skin-friendly mesh fabric follows the body comfortably while allowing airflow. A cotton-lined bottom and adjustable snap closure add extra practicality for longer wear.
