I followed the other reviewers recommendation and ordered several sizes up.  I was really glad I did because the 3X fit like an XL.  I ended up returning it because the way the sleeve fit near my elbow just didn't look right.  It was in between a 1/2 and 3/4 sleeve and just wasn't as flattering as my Heirloom shirts.  I also wished it was a bit longer.  It looked okay on me, but I didn't love it.  Otherwise, I liked the color and fabric.
