Question 1

Is a 42DDD the same in every brand?

Accepted Answer

No - a 42DDD isn't identical across brands, because brands use different sizing systems and cup depths. Here's how a standard US 42DDD translates in the brands we track: ThirdLove 42DDD, Wacoal 42DDD, Panache 42E, Bravissimo 42E, Freya 42E, Elomi 42E, Glamorise 42DDD, b.tempt'd 42DDD, Fantasie 42E. SHEFIT, Kindred Bravely, ENELL size by their own chart instead of band/cup.

Question 2

What are the sister sizes for 42DDD?

Accepted Answer

42DDD's sister sizes — same cup volume, different band — are 40F and 44DD. Try a sister size if the band feels too tight or loose but the cup still fits.
