I ordered this top in my normal size medium, and it was very large. i am 160 lbs, 36b, size 8 top and 12 bottom. it was so pretty, that i took a chance and reordered it in a small. the small on me fits just like the model in the picture. it's pretty lightweight, but is not see through. it is a very wide v-neck, but i am small on top, so it does not bother me. it's such a comfy yet sexy top!
