Do they do the dryers in different sizes? Otherwise you'd have someone trying to stretch an A-cup on the DD dryer, or putting the DD onto something more suited to an A and having it sag. (We don't want sagging DDs, do we?)
Also, what range of sizes, do they cater for the really well-endowed, given that this group are more likely to need costly support and want to take good care of it. Inquiring hands^Wminds want to know.
