I am 5'4 & 155lb. and I order 1X . It is not too big but actually nicely spacious but gives a sharp accent under the bust so that it is not too baggy. I love the way it drapes over your stomach and buttock to cover. Very smooth and not too thick that you can layer over long sleeve shirt. design pattern over one side of chest to the back has beads but not too shiny. I think I will order another one, in different color
