Well I do trampolining and I usually wear track suit bottoms with a t-shirt, You can where long sleeved shirts too, it's up to you! As long it's comfortable. Hope this helps & I Hope you have a great time! Good luck I'm sure you will enjoy it!
My daughter has been in trampoline for four years and they are required/ requested to wear leotards. They need to be able to see you body moving and a t-shirt and track pants would not be allowed exact first class at our gym. If you have fitted clothes similar to dance clothes that could also work, but no skirted Leo. If you are a larger girl or conservative and not comfortable in a leotard, wear slim fit cropped pants or leggings with a athletic top. Also tshirts are not ideal because they will lift up and expose your stomach or chest when jumping if not tucked it. Keep in mind you will be jumping with your arms raised over your head so also don't wear shirts to cropped or short. Very important for busty girls to wear a good sports bra.
Don't listen to the leotard nonsense unless your looking to be a world champion!! Just wear something that is fairly fitted to your body, it doesn't have to be skin tight. Maybes like a sportswear t shirt and some legggins. Similar to what you would wear to go running.
A possible leotard with leggins on top? This is easily wearble and you can simply add a hoodie/coat/jumper on top to look like a everyday outfit
Wear tight shorts and a tight t-shirt
Everything
