completely unraveled in the washing machine the first time I washed them!! I pulled them out in a huge ball of knotted up string and had to just throw them away. That was the biggest waste money I've ever spent.  If I could give less than 1 star I would.  But they were packaged nicely so I guess that gets a star.
Also, i should mention that nowhere on the packaging did it specify any washing instructions.  I wash other leg warmers in the washing machine so I assumed I could wash these as well.
Baby Legs and ruffle butts may cost a bit more but they are still in 1 piece.  Guess you get what you pay for.
