As expected, these Barely There bras were very comfortable.  However, they run EXTREMELY large.  I ordered an XL based on my 38D bra size and the proper fit of your average sports bra.  They were way too big.  According to the tag, a 38D falls somewhere between a Medium and a Large.  I ended up giving both to a friend who LOVES them. I would recommend them for comfort, but be careful about sizing.
