I wore these for practice and competitions in rhythmic gymnastics. They are made of velour fabric. I wore them when I was 158cm tall. The navy blue see-through leotard was worn a few times for less than a year. *Please check the photos. (Please comment if you have any questions) I have kept these at home for over a decade since I quit rhythmic gymnastics. I stretched them to check, but there was no damage to the fabric or elastic. This is based on my personal assessment, so please understand. Please purchase after you are satisfied. - Colors: Black, Navy Blue - Design: [No design information provided] - Brands: SASAKI, ALPHA FACTOR Thank you for looking.
