Everything you need to know

Is it shapewear?

No - the Body Belt, unlike shapewear that squeezes and compresses your body, works on your clothing, not on you. It gently shapes and tucks your outfit to smooth any bulk, define your waist and create a cleaner silhouette.

Will it roll or dig in?

Not at all. Made with soft, ultra-stretchy fabric, the belt sits comfortably on the body and moves with you. It doesn’t pinch, roll or cut in like traditional shapewear can.

What can I wear it with?

Pretty much anything. It works under tees, knits, dresses, blouses and blazers. Wear it at the waist to tuck and define, at the hips to smooth, or under the bust to add shape to oversized styles.

Does it work if I'm bloated or my body fluctuates?

Yes - that's exactly who it's designed for. Because it adjusts fully and works on your clothing rather than compressing your body, it works with you on every kind of day.

What size does it fit?

One size fits all. The Body Belt fits AU 4–26 (US 0–20, UK 2–22, EU 30–52) thanks to its stretchy fabric and adjustable built-in slider.

What's the difference between this and the Styling Kit?

The Starter Pack includes both Body Belts (beige + black). The Styling Kit adds Garment Liners for sweat protection and Sleeve Garters for polish - everything you need to solve every outfit problem at once.
