Shapewear briefs

Looking to smooth your silhouette and give your curves the best? Choose shapewear knickers, designed to reshape your figure while offering genuinely comfortable all-day wear. Contrary to popular belief, shapewear knickers have nothing to do with old-fashioned "granny pants": our technical microfibre fabrics hug the body with a second-skin feel, delivering a real flat tummy effect.

In practice, a shaping panty or control brief works through a denser knit than a regular pair of knickers. This fabric applies gentle, progressive pressure to the areas you want to smooth, while staying stretchy enough to move with you throughout the day. Seamless finishes and flat-sewn elastics keep your shapewear knickers invisible under clothing, even under fine or figure-hugging fabrics.

What are shapewear knickers and how do they work?

Shapewear knickers gently smooth the tummy, hips and bottom through their technical knit, without ever squeezing. The best styles combine real support with lasting comfort, so you forget you're wearing them by the end of the day.

The different levels of support (light, medium, firm)

Across the shapewear market, you'll generally find three levels of support: light, medium or firm:

• Light support: medium to high coverage and a soft knit, gently smoothing your silhouette for everyday wear, with no compressed feeling.
• Medium support: the most versatile level, with a reinforced tummy panel and a supportive waistband for a noticeably smooth yet comfortable effect all day long.
• Firm support: double-layered fabric (particularly at the thighs) and non-slip bands, for a more pronounced smoothing result exactly where you need it most.

At Sans Complexe Paris, the right level really comes down to your own comfort and the occasion: medium support for everyday wear, firmer support for times you want a more visible effect under figure-hugging outfits.

Why choose Sans Complexe Paris shapewear knickers

As a specialist in extended-size lingerie, Sans Complexe Paris offers a wide range of shapewear knickers from UK 10/12 to 26/28, designed for every fuller figure. Every style combines real support with lasting comfort, never sacrificing style: floral lace, nude or black tones, and satin-finished trims give our shapewear knickers a feminine touch.

To discover the full range, head to our shapewear collection, featuring panties, shaping briefs and high-waisted shapewear knickers.

A range designed for every figure

Our extended-size range goes far beyond the usual market standards, which too often stop at 2XL. With us, every figure finds the right extended-size shapewear knickers, with a genuine choice of cuts: classic briefs, full-coverage panties, or high-waisted shaping briefs for extra tummy support. To complete your set, you'll also find our extended-size bras, designed to pair perfectly with your shaping knickers.

How to choose the right shapewear knickers

The right choice comes down to three main factors: your figure, the effect you're after (flat-tummy shapewear, a smoother bottom, or an overall more defined silhouette) and the support level you want. High-waisted shapewear knickers work particularly well if you want to cover and support the whole tummy area, while a panty or classic brief suits a more discreet, everyday level of support.

Size guide and fit tips

To choose the right size, go by your usual knicker size: our styles are designed to fit true to size, with no need to size up. If in doubt, our knicker size guide walks you through finding the ideal balance between comfort and support.

Which shapewear knickers to wear with your outfit (fitted dress, skirt, trousers)

Under a fitted dress, go for a style that's invisible under clothing, with seamless finishes and a flat-sewn elastic to avoid any visible lines. Under a skirt or close-fitting trousers, high-waisted shapewear knickers give fuller tummy support. For an even more discreet everyday look, check out our high-waisted knickers and our invisible knickers, designed to disappear completely under your clothes.
