Find Your Fit

Use this guide as a general reference. Measurements and conversions vary by brand; each product’s size chart and fit notes take priority.

1. Women’s Clothing

For tops, dresses, sets, and outerwear, start with your usual letter size and compare your measurements with the product’s own size chart. Fit and stretch vary by brand and style. Product-specific measurements and fit notes take priority over a general chart.

Measure your bust, natural waist, and fullest part of your hips.
Check whether the listing shows body measurements or garment measurements.
If between sizes, use the listing’s stretch and fit notes, or contact us for help.

Boutique Denim Sizing

Some denim styles use odd-numbered sizes. As a starting point for those styles, an even U.S. size 2 corresponds to boutique size 1, size 4 to 3, size 6 to 5, size 8 to 7, size 10 to 9, size 12 to 11, size 14 to 13, and size 16 to 15. This conversion does not apply to tops, dresses, letter sizes, or plus-size denim labeled 14W–24W.

Always follow the specific Judy Blue, Risen, or RFM listing’s measurements and fit advice. Check waist, hips, rise, and inseam before choosing your denim size.
