These shorts are definitely for the minimalist.  The skinny minimalist, that is.  I am a size 0 and hardly have a butt.  I can get by with wearing these shorts but just barely.  I got a size S and wish I would've gotten a M.  They fit more like boy short bathing suit bottoms (length wise).  They are VERY low rise (you need to be hair free) in the front AND BACK.  I was very worried my crack would be exposed, but I pulled them up and tied the drawstring and they stayed up and hovered just above my crack.  Padding is very thin, like tri shorts, so a long ride would not be too comfortable.  I wanted something to reduce tan lines, and I got it.

Shorts run true to size, but are a bit short to be considered shorts - they are definitely micro!  They fell lower on the waist (which I find more comfortable).  However, they covered enough (with a long tank top) of my rear to provide me with enough coverage to wear them without shorts over them for the bike and run. Perfect for any woman doing a triathlon who wants more coverage than a bikini bottom.  Padding was sufficient for the 17 mile bike.  Drawstring helps to keep the shorts from riding down at the waist.  Didn't ride the legs.  Dried quickly.  Loved the bright color!
