3D printed velvet adds support, and a bonded underbust lifts without underwire. Adjustable straps and back closure let you modify your fit. Straps can also be crisscrossed to stay hidden under racerback tank tops. Runs true to size, but if you're in between sizes or our sizing tool recommends a size that's smaller than what you would usually wear, we recommend sizing up. Removable cups with a slightly thicker apex are included for modesty and also provide a nice shape under clothing. Body: 64% Nylon, 36% Spandex Worn once and washed on delicate cycle.
