Ask the coaches; they'll know what the local rules and regulations are.
I think you will be ok for the classes, but in higher levels, anything but a leotard and shorts can easily get caught in the equipment!! Be aware that once you start competing, you HAVE TO WEAR A LEOTARD! it's regulations!. So I would say go and try it, but you won't be able to go far if you can't wear a leotard
Asalamu alaykum sister. Mashallah Your clothing is fine and halal don't worry. I wish you luck in your gymnastics.
You'll be fine in that! Also, you could wear just a leotard(if ok). Other than that I thing you'll be great in that!
yes you can the one thing you should make sure is that the pants aren't too long because you don't want to hurt yourself while doing a skill.
I think you should be ask your coaches,if he will give you permission,then you can wear.
