I really like this leotard as a more interesting summer option that the plain one. However, I have had a hard time getting the neck and armhole openings just right. I've had to be careful and attach the foldover elastic with very little stretch - the whole first batch no one could get on through the neck whole! I ended up narrowing the contrast piece in the back to increase the size of the neck whole. Then, the underarm on the side of the contrasting fabric was too tight and had to be lowered. But in the end the girls seem happy with them! My advice with this leotard would be to pin the contrast piece on the main body, then have your gymnast try it on. Do this after you put on the foldover elastic, but before sewing the contrast piece onto the main body.
