This item came fast, but I quickly discovered why it's called the No Slip, No Ride-up bra.  It is literally two sizes too small, it doesn't move because it CAN'T move.  I ended up giving it to my daughter who wears a 34c (the bra was a 36d).  I have had good luck with other Playtex bras in the past, this was very, very disappointing.
