These were so comfortable that I ordered a second pair.  They also go into the XL size.  I would order 1 size above your normal size which I did unless you like a really tight fit, which I don't.  They are a smooth comfortably hugging fabric, which stays in place in all the right places.  Nothing to be ashamed  about if your husband or boyfriend sees you in these.  I hand washed them with  a little hotel shampoo in the sink, at 11:00PM , hung them up  in the bathroom/shower, and they were dry at 8:00AM the next morning.  I wish they made a bra just like this but with a little support in the cups and I would buy the bra's also.  You could easily travel the globe with 2 pair.  I see no evidence for fraying but have only washed them 4 times by hand.  The stiching and construction looks well made.  They are true to their description.
