I ordered these in black and size small. I have slim hips and the shorts are very snug even for me. They don't stretch a lot. I suggest washing them by hand or turning them inside out and using the gentle cycle. Then hang to dry.
I had to order these shorts in Silver for my school musical last year for the main dancers group, there was 6 of us. I was so impressed at how awesome they looked when they arrived, and they were so reasonably priced - we were expecting to have to pay about double to get silver shorts for the show! When they arrived, they looked as if they were made for a 6 year old (we had ordered sizes S and M) so I was a bit worried that we may have to send them back for larger sizes, but they are so super stretchy! They are so good because not only do they look super cute on stage, they hold everything (tummy and butt) in.
I absolutely loved my pair that I had, and have worn it to MANY dance classes since, over a leotard, and always have gotten compliments about them. The only thing I wish about these shorts is that they were machine washable - which I found out the hard way! I was super silly and didn't read the care instructions, and kept chucking them in the washing machine with all my other gear, and the silver has now come off in patches on them :(
I'm still ordering another lot of them, in all different colours, because I love them so much, and now I know HAND WASH!!!!
