Okay so I needed to "refresh" my undie drawer... I'm in my 40's and consider myself fashion-conscious and stylish... however, of recent I took a good look at my lingerie drawers and realized it was time to get rid of some things I was never wearing; you know throw out those things that needed to go and buy some new stuff.  So, to make it easy, I turned to amazon and ordered a few different name brands of underwear but all similar styles (hipsters), and I can say I just love the Kalon nylon spandex pairs.  I did read the reviews before ordering and got a size down from what I normally would and they fit perfect.  Although I cannot comment on the longevity since they are all new yet, I do feel that they have lasting power and they are SUPER comfy.  They also look nice - sporty but cute.  I would highly recommend.
