I'm an xl in all retailer tops, and sometimes the xl are still too small to fit loosely; i don't like to wear tight clothes. having said that, i had to purchase this top in a size small because it was just cut so large. the sleeves hang a bit odd if you don't get the correct size. i love the feel of the blouse, the fabric is a nice quality. i recommend giving it a try but have patience during the process of figuring out the size that will look best on you in this blouse.
