Sister sizes of 44DD
42DDD and 46D hold a similar cup volume to 44DD with a tighter or looser band. If the band of a 44DD rides up, try 42DDD; if it digs in, try 46D.
Deep cups on standard bands are well covered by full-bust specialists and increasingly by mainstream brands' extended ranges — but cut quality varies enormously. Prioritise firm bands (the band does most of the work, and that matters more with more weight to support), side support panels that keep tissue forward, and top edges that don't cut in. If straps dig, the band is almost always the real culprit.

What is 44DD in European sizing?
A 44DD corresponds to 100E in European sizing and 115E 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 44DD big or small?
It is a full-bust size: a deep cup on a standard band, well served by specialist lines. Cup letters mean nothing alone: a cup only has a volume relative to its band, which is why 42DDD and 46D hold a similar volume to 44DD.
My 44DD doesn't fit — what should I try?
If the band rides up or feels loose, go to 42DDD. If the band digs in while the cup is fine, go to 46D. 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.
