Best Shapewear for Thighs: Smoothing & Anti-Chafe for Plus Size

Plus size thigh shapewear laid flat: capri shaping leggings, long-leg shaper shorts and padded shaping shorts

The short answer: the best shapewear for thighs has a longer leg that ends below the fullest part of your thigh, a wide, flat grip band so it doesn't ride up, and a high waist so your tummy stays smooth too. Mid-thigh shorts work for most dresses. Capri-length styles give the most smoothing and chafe protection.

Thigh shapewear smooths and holds while you wear it. It doesn't slim your thighs permanently. It creates a smoother line under clothes and a barrier that helps stop skin rubbing.

Who this is for

  • Your thighs rub together under dresses and skirts
  • You want a smoother line under fitted skirts, knits and trousers
  • Your shorts keep rolling up your legs
  • You want thigh smoothing and tummy control in one piece

What to look for

The right leg length

  • Mid-thigh: good for most dresses and skirts that hit at or below the knee
  • Above-knee: more smoothing and chafe protection, and less chance of a line across the widest part of your thigh
  • Capri: the most coverage, best under trousers and midi or maxi skirts

Grip that stays put

Look for wide, flat or silicone-lined leg bands. Narrow elastic edges roll and dig, especially on fuller thighs.

A high waist

High-waisted styles smooth your tummy and stop the waistband cutting in when you sit.

Smooth, breathable fabric

Soft, smooth fabric reduces friction between your thighs and stays comfortable in warmer weather.

Fit and sizing tips

  • Measure your waist, hips and thigh at the fullest point and compare them with each product's own size chart. See our plus size sizing guide.
  • Size up if the legs dig in. Tight leg bands cause the bulge and roll you're trying to avoid.
  • Walk and sit in them. Good thigh shapewear stays in place without tugging. Read how tight shapewear should be.

Common mistakes

  • Legs too short. A hem at the widest part of your thigh can create a visible line.
  • Too tight at the leg. It squeezes and rolls instead of smoothing.
  • Low-rise shorts. They leave a ridge at your tummy. Go high-waisted.
  • Hems showing under short skirts. Match the leg length to your hemline.
