One of the most common emails I get is from women looking for bra cup sizes beyond the standard A, B, C, and D that the average lingerie retailer carries. Here are a few online companies that carry bras that hold a little more and the sizes they have to offer:
Bigger Bras - The largest cup size I found was L. They have combo cup sizes, i.e. G/H. The largest double cup they have is JJ.
