This is the second pair of these which I have purchased, the first white pair looked so good on my girlfriend that I had to get a pair of red ones.

They look incredible on her, she's around 5' and they fit fine, I was worried they may be a little long since she's so short but they're a perfect fit.  The stay up top works really well as they do stay up on their own.  A garter belt is definitely not needed but of course can be added for extra visual appeal if you like.  Also, the lace top makes them look much sexier than plain stockings.  They are definitely sheer enough, her painted toe nails are easily visible through the material.

The first pair have been worn at least a dozen times and are still in pretty good condition.  The second pair look just as good and there will likely be a third pair before too long.  If your guy likes stockings or you're a guy who likes your girl in stockings, these are definitely a worthy purchase.
