I can't, for the life of me, understand why people like this brand.  I bought one, loved it - bought about 10 more colors - all before washing the first one.  They wash up HORRIBLY.  In a lingerie bag, washing by hand .... doesn't make any difference.  They pill and look like crap after the first washing.  My white and off-white ones I threw away after the first washing.  Darker colors I kept a little longer.  But they look horrible, and I will only wear them under something where you can't see all the loose pills.  Absolutely hate them and wish I'd never bought the first one.
