They are a great fit and feel super comfy.  I would recommend to only buy these if you are going to wear them under a dress because they are a bit see through.  I wore them with black undergarments but you could still tell they were see through.  Other than that they are fine.  I bought them with the intention of wearing them under dresses so no biggie.  Or you could also wear them alone if you have a long enough top to cover your back.
