I ordered a 36DD because the first Wacoal bra I bought in a 38DD fits best on the tighest hook and eye so I was thinking the 36DD would be the best choice , especially if , like most bras it stretches out after washing and wear.  However, there is no "middle ground": I can't do it up at all.  So I will be returning it and requesting the 38DD, hoping that it will not stretch out and become loose.  I guess I'm surprised that the sizes do not have any overlap.

Please note that this review for some unknown reason is appearing under my husband's name.  The bra IS mine!
