Question 1

Is a 46O the same in every brand?

Accepted Answer

No - a 46O isn't identical across brands, because brands use different sizing systems and cup depths. Here's how a standard US 46O translates in the brands we track: ThirdLove 46O, Wacoal 46O, Panache 46K, Bravissimo 46K, Freya 46K, Elomi 46K, Glamorise 46O, b.tempt'd 46O, Fantasie 46K. SHEFIT, Kindred Bravely, ENELL size by their own chart instead of band/cup.

Question 2

What are the sister sizes for 46O?

Accepted Answer

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