Size Chart

Need Help Finding the Right Size?

Every body is different, so a size chart is only a starting point. The quickest way to find your JulieMay size is our AI fit quiz: tell it how a bra you already own fits, or use a tape measure, and it works out your band and cup size in about two minutes (watch the short guide at the bottom of this page). Prefer a person? Book a free virtual fitting with our specialist Amanda, or visit the Bra Fitting Room for measuring tips, fitting tips and style recommendations for your shape.

If you'd rather measure yourself, use the charts below. Measure over a thin, unpadded bra, keep the tape level and snug, and if you're between band sizes choose the snugger one.

Skip the tape measure: let the AI fit quiz find your size

Size charts are a good starting point, but around 80 percent of a bra's support comes from the band, and most women are wearing one that is too loose. Our Brarista fit quiz, co-created with expert bra fitters, checks how your current bra actually fits and works out your JulieMay size in about two minutes. No bra to check against? It can fit you with a tape measure instead, or recommend the best style for your shape. This short video shows how each option works.
