Sizing, simplified.
We threw out the band-and-cup system. No tape measure, no fitting room, no PhD required. undun uses volume-based sizing — two options that fit real bodies, A through G.
Light Volume
Generally fits A – D cups
Medium Volume
Generally fits DD – G cups
We built a completely new sizing method.
Our sizes are nothing like outdated apparel. Find your perfect match in 60 seconds.
