The generic product description says that there are only 3 rows of hooks. Once you move up to the 38DD size, there are 4. I know that an extra row doesn't sound like a lot, but it makes a huge difference regarding the width of the backstrap. I went back to a 36 b/c I just wanted the three rows of hooks. If you can stand the 4 rows, this is a great bra for women with smaller frames and larger breasts. I found a good amount of support while still having a little movement. Most bras my size are granny-approved, so it is nice to have a lacy one that looks fresh.
