Question 1

Is a 36DD the same in every brand?

Accepted Answer

No - a 36DD isn't identical across brands, because brands use different sizing systems and cup depths. Here's how a standard US 36DD translates in the brands we track: ThirdLove 36DD, Wacoal 36DD, Panache 36DD, Bravissimo 36DD, Freya 36DD, Elomi 36DD, Glamorise 36DD, b.tempt'd 36DD, Fantasie 36DD. SHEFIT, Kindred Bravely, ENELL size by their own chart instead of band/cup.

Question 2

What are the sister sizes for 36DD?

Accepted Answer

36DD's sister sizes — same cup volume, different band — are 34DDD and 38D. Try a sister size if the band feels too tight or loose but the cup still fits.
