Don't put anything in your pocket!
I bought the yellow pair on vacation last week and loved them! i wore them home on the plane and had a pony tail holder in my pocket (basic goody binder), and there is a circle stain where the binder was! so strange! i sprayed them with spray and wash and washed them. the stain is still there and now it is discolored in the area i treated them! they are ruined! i am so disappointed and i only got one wear out of them!
