Does Victoria's Secret and Aerie carry AA bra size in stores?

I'm thinking of buying a bra for a younger teenage girl, in which a AA bra would be appropriate. She does need one, and I understand that VS and Aerie carry the cuter prints, appropriate for a girl her age. I do want her to try them on first. However, do they carrie the AA bras in stores? She measures 27" on her chest, and 32" on the bust. All assistance is welcome, and thank you very much!
