Question 1

Is a 38DDD the same in every brand?

Accepted Answer

No - a 38DDD isn't identical across brands, because brands use different sizing systems and cup depths. Here's how a standard US 38DDD translates in the brands we track: ThirdLove 38DDD, Wacoal 38DDD, Panache 38E, Bravissimo 38E, Freya 38E, Elomi 38E, Glamorise 38DDD, b.tempt'd 38DDD, Fantasie 38E. SHEFIT, Kindred Bravely, ENELL size by their own chart instead of band/cup.

Question 2

What are the sister sizes for 38DDD?

Accepted Answer

38DDD's sister sizes — same cup volume, different band — are 36F and 40DD. Try a sister size if the band feels too tight or loose but the cup still fits.
