I love this blouse!! I read the reviews before buying so I sized down. I'm 5'8, 132lb and normally would wear a small/medium, but ordered an extra small and it's perfect. It is thin as stated in other reviews, but fine with a cami under or a nude bra. I just got it today and can't wait to wear it!
I'm 4'11" and ordered a small. Blouse fits great but as per usual with blouses that have little "give" to them, it can be a struggle to get off (no issues getting the blouse on though). The back is sheer so a cami would just need to be worn underneath.
I love this top! I get compliments on it each time I wear it. I love that the looser fit makes it flattering in all of my "problem areas" as well. It is made of a lightweight material, but isn't see through.
