Our Fit
At a space, in between., every garment begins with the body in mind. We fit our patterns on Alvanon’s custom American US W20 women’s plus-size form, then apply our in-house biomechanics expertise to grade and refine each size—ensuring the same comfort, drape, and elegance from 1X through 6X.
Our goal: that moment when you put on your garment and feel instant joy, freedom, and confidence.
How to Measure
Chest
Measure around the fullest part of your bust, keeping the tape level.
