Size Guide - Adult underwear bottoms

Sizing for all RUBIES adult bottoms should be close to standard US Women's sizing. If it seems far off of what you would have expected, contact us through our chatbot on the bottom left of our website.

Measure all the way around the waist just under the belly button. Pick the size based on which waist range it fits in.
