Orrpally Women Bath Wrap Spa Towel with Hair Towel Adjustable Closure Shower Robes lightweight Towel Wrap for Women

Is this made of cotton?

Any advice on how to wrap up the turban? No photos or directions with the product, and it's not all that obvious to me. Thanks!

I’m a size 8. What should I order sm/med or large

Description states 100% terry cloth and terry cloth is made from cotton. just verifying these are indeed terry cloth/cotton 100%
