Sizing Guide

Size matters! Here's how to find your Willow size

Coin Method

  1. First, stimulate your nipple until it perks up (don't skip this step!)

  2. Hold up a dime, nickel and quarter to compare each coin against the diameter of the base of both of your nipples, not the areola (see diagram below)
