These are not unisex unless you are a very big girl.  I got one for my husband and me and they are way too big.  He said the L is for a guy that weighs about 300 #s.  He weighs 180.  The weight and construction seemed fine, but the sizing is off.  I am 5'4" and usually weigh a L and this robe hit the floor and was just too big all around.  I ended up going to Land's End and getting a Petite Large and it fits perfectly.
