“I love this top so much!! I’m 4’9” and 95 lbs. The xs is perfect! I LOVE the open back. This is my first long sleeved work out top which sounds ridiculous but it’s because I didn’t think I’d like working out with long sleeves. This was on sale so I gave it a try and now I’m excited to have it for winter. Make more like this please and don’t change the sizing! Haha! The fabric is incredible (like all P’tula everything else) so it’s really comfortable. I can’t wait to see what other long sleeved designs you create!”
