This is the most softest unique material blend I have ever felt. It’s called sleeping on snow for a reason. It feels so slinky soft on the skin, words are hard to describe. This is ONE SIZE. It looks good on all sizes from XS- 2x depending on chest size. I would say Ivory/off white/eggshell color along those lines, just not white. Pit to pit-22” (look at pic to see how it’s measured) Shoulder to hem-23” All sales are final.
