Sister sizes of 44B
42C and 46A hold a similar cup volume to 44B with a tighter or looser band. If the band of a 44B rides up, try 42C; if it digs in, try 46A.
With this profile, fit quality is often the bigger challenge — small cups on standard bands are often cut for a rounder shape than many bodies have, so gaping at the top edge is common. Balconette and demi cuts tend to follow a shallower curve better than full-coverage styles, and a band that stays put matters more than the cup label.

What is 44B in European sizing?
A 44B corresponds to 100B in European sizing and 115B in French/Spanish sizing, by the usual correspondences. The conversion changes the band numbering, and from DD up the cup letter too (US DD = EU E); individual brands can differ.
Is 44B big or small?
It pairs a standard or larger band with a shallower cup. Cup letters mean nothing alone: a cup only has a volume relative to its band, which is why 42C and 46A hold a similar volume to 44B.
My 44B doesn't fit — what should I try?
If the band rides up or feels loose, go to 42C. If the band digs in while the cup is fine, go to 46A. If the cup overflows, try one cup up in the same band; if it wrinkles empty, one cup down. Two minutes with the calculator gives you a fresh estimate.
