I had the opportunity to be fitted at a My Intimacy shop. This is the group that has been on Oprah and they gave me a great fitting and I can wear under wires and they are comfortable. I measure a 32 C which isn't a size at target or Walmart or even Kohls. A 34 B is more common but it doesn't fit me correctly. Places like My Intimacy will also alter bras if necessary. Even though I am not "well endowed" I still wear a bra every day.
