Question 1

Is a 34AA the same in every brand?

Accepted Answer

No - a 34AA isn't identical across brands, because brands use different sizing systems and cup depths. Here's how a standard US 34AA translates in the brands we track: ThirdLove 34AA, Wacoal 34AA, Panache 34AA, Freya 34AA, Elomi 34AA, Glamorise 34AA, b.tempt'd 34AA, Fantasie 34AA. SHEFIT, Kindred Bravely, ENELL size by their own chart instead of band/cup.

Question 2

What are the sister sizes for 34AA?

Accepted Answer

34AA's sister sizes — same cup volume, different band — are 32A. Try a sister size if the band feels too tight or loose but the cup still fits.
