Its cute and did the job for the costume night we needed it for. Would we wear it on a regular basis or use it for gymnastics? no.The side seams comes up really high into the armpit. It's not sleeveless like you expect tank style for a leotard. More like the sleeve is cut straight down instead of on an inward curve. It makes the arm hole really small and uncomfortable. Did I mention it is cute and sparkly? Thats counts.
