I'm 5'5" 108lbs and small 32B. I got the regular XS in yellow and black and it fits exactly as pictured on the first model wearing yellow with her hair dirty blonde hair to armpit. As pictured, it is not skin tight and lays on upper hip and flares out at bottom. It is a thick cotton material and ve...ry soft. It looks like it will wash well. The yellow is not see through but I could tell I was wearing a dark bra under it. I appreciate how there is no gapping between the buttons and the buttons are very secure. The black top looks cute with a short sleeved ribbed shirt under it. I also left the bottom button undone so my jean shorts showed more. It can be dressed up or down. The black one can easily carry over into all seasons if layered. The cut is perfect for lying on top of a high waisted or low rise bottoms. I ordered the black petite XS to compare and it provides a more snug and shorter look that is more revealing. The torso is cut long so petite works for my height in this shirt.
