Question 1

Is a 28L the same in every brand?

Accepted Answer

No - a 28L isn't identical across brands, because brands use different sizing systems and cup depths. Here's how a standard US 28L translates in the brands we track: ThirdLove 28L, Wacoal 28L, Panache 28HH, Bravissimo 28HH, Freya 28HH, Elomi 28HH, Glamorise 28L, b.tempt'd 28L, Fantasie 28HH. SHEFIT, Kindred Bravely, ENELL size by their own chart instead of band/cup.

Question 2

What are the sister sizes for 28L?

Accepted Answer

28L's sister sizes — same cup volume, different band — are 30K. Try a sister size if the band feels too tight or loose but the cup still fits.
