OSIAS Size Guide

The OSIAS clothing size chart is based on flat measurements of the garments, including essential dimensions such as bust, waist, and hip measurements. Some items may also include shoulder width, garment length, and pant length.

To help customers make more confident choices, OSIAS provides flat model fitting data, which is reflected in the size chart.
