Question 1

Is a 48DDD the same in every brand?

Accepted Answer

No — a 48DDD isn't identical across brands, because brands use different sizing systems and cup depths. Here's how a standard US 48DDD translates in the brands we track: ThirdLove 48DDD, Wacoal 48DDD, Panache 48E, Freya 48E, Elomi 48E, Glamorise 48DDD, SHEFIT 48DDD, b.tempt'd 48DDD, Kindred Bravely 48DDD, ENELL 48DDD, Fantasie 48E.

Question 2

What are the sister sizes for 48DDD?

Accepted Answer

48DDD's sister sizes — same cup volume, different band — are 46F and 50DD. Try a sister size if the band feels too tight or loose but the cup still fits.
