If you are a C or D cup they are comfortable and supportive. Instead of the wire inside I like the compression sport bras that they have at Nike. They are supportive and very comfortable.
You can find comfortable bras at Wal-mart and Target. They sell cheaper comfortable bras. Victoria's Secret also has comfortable bras, but they are a little bit pricier.
For a girl just starting breast development (maybe a raised nipple or slight bump) I would not recommend a cup bra. It is important that your breasts fill the cup, and training and sports bras are much more comfortable at a young stage. I measure at a 34b cup, and I still prefer training and sports bras, but it is a matter of opinion. While you're at the store, try on a bunch of bras! Training, sport, cup, whatever is the most comfortable.
No, they do make 32AA cup bras. It may be, however, easier and more comfortable to wear a fabric bra with support for that particular size.
if you mean open cup bras they are a type of bra Im not sure what they are made for but I think they are supposed to make your boobs look bigger and they hold them up but they dont cover your breast.
Seriously! Kids don't need cup bras!
Yes they are very comfortable if you wear the appropriate size
Comfortable bras can be found online and in stores. Hanes sells bras that are comfortable at stores like K-Mart, Walmart, and Target. The Genie Bra can be bought online from Amazon and is reported to be fairly comfortable.
You can find Carole Marin's bras at Wal-Mart. These bras are marketed to be the most comfortable bra you can find.
It is logic for girls to wear cup shaped bras to cope with shape of their breasts.
One can purchase G cup bras online from a number of retailers. Bras of this size can be purchased from 'Brave Lingerie', 'Soma Intimates', 'Bravissimo' and 'Debenhams'.
Bras that contain a thin wire in the underside of the cup for added support and lift.
