Size Guide
Find your fit before you check out. Bottoms, bras and tops are body measurements, so measure yourself and match the closest range. Tees are measured laid flat, so compare them with a tee you already own. Bodies are beautifully unique, so treat this as a guide.

Aura Peachy Rise
The Aura Peachy range comes in two rises. The High Rise waistband sits 4cm (1.5") higher than the Mid Rise for more coverage and core support.

Both rises use the same buttery Aura Peachy fabric and sculpting scrunch. The only difference is how high the waistband sits.
