They are very nice and classy, maybe they are a little tigh, but that depends on how you like to wear underwear, so you may consider buy them one size up depending to your likes of course. For you to have an idea, I am a 5'6, bought them Size S and they fit perfectly but a bit tight as told, but very usable thou. But I like them that way, and if you workout and have a nice body, trust me, you will love to show off your chic every time you can. ;)
