This is one of my favorite designs and maker of tunic tops.  I now have 5 colors suze XL it fits 42.5 bust. Im 5ft1in 145lbs and its a perfect fit. Its designed to give you a shape without sqeezing you into shape. Its the design. It is beautiful, light weight, not see through, (but so far white is), and it comes in at the bust and flares at the waist. If you have a larger waist or post baby bump go one size up. The bust is made to stretch or gather within reason.
