YOFITWomen Yoga Shorts Ruched Butt Sport Gym Push up Running Elastic High Waist Shorts Butt Lifting Hot Pants #1 Black S

Are these squat proof?

What size should I get? I am 5'1, 26 inch waist, 110 pounds. Pant size 2-4 (size 4 too big in waist & too long but size 2 is tight on thighs)

I’m a mtf preop transgender individual will these fit

Of what are these made - polyester/spandex or nylon/spandex? Thank you
