It was a good recommendation to size up, I'm normally a medium but the size large fits great. I'm 5'4" 153 lbs and a size 29 in jeans for reference. Lots of compliments on how cute these are! They are pretty short and during a WOD I do find myself pulling them down in the back a bit to recover some of my rear/legs.
I love the fabric and the compression they give. Design is amazing!
