For reference I am 5'3" 110 lb 34 chest. I bought size small in the beige.
Pros: Love the style! The sleeves flatter your arms by showing off your shoulders and upper arms yet hiding any sagging "batwing" areas that we mature ladies might have ;)
Cons: I don't know if it is just the beige color ( which is more of an ivory color) but the fabric of my top is not very soft. Actually kind of scratchy and not very stretchy at all. I may try a different color to see if it makes a difference.
Though it fit me well, I also may size up to medium due to the lack of stretch in this one. I'm giving this cute summertime top 4 stars.
