Size Guide
Onni & Aggi garments are designed to sculpt, elongate, and move with the body. Each piece is developed with intentional fit, stretch fabrics, and platform-ready proportions in mind.
Our Fit Philosophy
Most garments feature stretch and a body-skimming fit.
If between sizes, choose based on your preferred level of compression.
Inseam lengths are designed with platform footwear in mind. Certain styles may include additional fit notes for longer torsos.
