How to Find Your Lingerie Size (and Why Fit Varies by Style)

 

 

Comfortable lingerie starts with the right fit. Here's how to choose your size with confidence, whether it's your first Peachez order or your fifth.

1. Start with your usual size

Our pieces use US sizing. If you know your usual US or UK clothing size, that's your starting point. Not sure? Our size calculator will help.

2. Read the fit note on every product

Different fabrics stretch differently, so fit varies from style to style. That's why every product page tells you honestly whether a style runs small, large or true to size. For example, some of our lace thongs fit small and we recommend one or two sizes up, while many of our other styles are true to size.

3. Check the stretch rating

Each product also has a stretch rating out of 5. A 5/5 seamless brief will hug and move with you. A 1/5 or 2/5 lace or velour piece has less give, so if you're between sizes, go up.

4. Bralettes, thongs and briefs fit differently

  • Bralettes: the band should sit flat and level without digging in, and the straps shouldn't slip or press.
  • Thongs: the waistband should lie flat without rolling, with no pinching at the hips.
  • Briefs: look for smooth coverage with no gaping at the legs or cutting in at the waist.

5. Buying a set? Choose each size separately

Lots of us are a different size on top and bottom, and that's completely normal. With our Dreamy Sets you pick your bralette size and your bottom size separately, so both pieces fit just right.
