I am 5'0" - 120 lbs.
I got a size Extra-Small.
The top fitted fine on me - I do like the push-up it gives me.
The bottoms on the other hand - were a little too small -- I don't think I have that big of a bottom but I think I would need a small or medium bottom.

I loved the floral pattern I got - they have several different solid colors to choose from as well.
