Underwear Sizing Chart

Find Your Perfect Fit

Hi there! I’m Madonna, the founder and designer of Eco Intimates, and I’m here to help you find the perfect fit for your lingerie.

The sizing chart below is specifically for our Stretch styles, including the Base and Luxe underwear ranges. These styles are designed with a soft stretch organic cotton containing 10% elastane, offering flexible support and comfort across the hips and waist.

If you're shopping for our Ruffle Knickers, please scroll down to view the separate chart below, as their fit and fabric differ from the stretch styles shown here.

Size	Flat Waistband (cm)	Fits High-Hip of (cm)	Stretches Max Over Bum, Hips or Waist (cm)
XS	61	89	up to 95
S	66	94	up to 100
M	71	99	up to 105
L	76	104	up to 110
XL	80	109	up to 115
2XL	84	114	up to 126

Ruffle Knickers Sizing

Our Ruffle Knickers are made from a beautiful woven fabric with no inherent stretch. However, they’re designed with elastic at the waistband and around the legs to ensure a soft, flexible fit. Because the fabric doesn’t stretch like our Base and Luxe underwear ranges, the sizing and fit feel different—so we’ve created this chart just for them.

Below you’ll find the relaxed flat measurement, the maximum waistband stretch, and the recommended high-hip measurement to help you choose the right size. If you’re between sizes or prefer a roomier fit, we suggest sizing up for added comfort.
