Plus Size Fit Guide

Plus size clothing, designed for you: our fit guide

When we first started developing PLUS in 2015, we conducted extensive market research, working with a plus-size model on initial fittings and consultations, then having the prototypes tested by two additional plus size fit models to ensure that they were comfortable and the right size. All items in the PLUS range are graded specifically for the plus size figure and are fit on larger bodies before launching to the public.

All of the garment measurements represent the measurements of the actual clothing. Scroll to the bottom of the page to see our sizing chart, which includes body measurements.
