Is a 44K the same in every brand?

No — a 44K isn't identical across brands, because brands use different sizing systems and cup depths. Here's how a standard US 44K translates in the brands we track: ThirdLove 44K, Wacoal 44K, Panache 44H, Freya 44H, Elomi 44H, Glamorise 44K, SHEFIT 44K, b.tempt'd 44K, Kindred Bravely 44K, ENELL 44K, Fantasie 44H.

What are the sister sizes for 44K?

44K's sister sizes — same cup volume, different band — are 42L and 46J. Try a sister size if the band feels too tight or loose but the cup still fits.
