Comfortable and decent material for the price.  It's stretchy, so it's easy to roll up or scrunch up the sleeves.  The buttons are rubbish, and it looks a bit weird buttoned up.  The tags on the blazer are in Asian sizing, so I size 6 says "XL".

Almost forgot to discuss sizing! I typically wear a small and went for the size 6.  I'm 5'2" and 135 lbs and the size 6 fits well.  I can button it comfortably, but it lays weird (I'm a C cup).  I prefer it open so I'm okay with that.
