Sister sizes of 46DD

44DDD and 48D hold the same cup volume as 46DD with a tighter or looser band. If the band of a 46DD rides up, try 44DDD; if it digs in, try 48D.

44DDD

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 80% 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.

Who makes 46DD? 95 of the 632 brands in the Cherry Size catalogue are confirmed to carry 46DD in their standard range. But each of them cuts it differently — the app tells you the exact size to try at every one of them, from your own measurements.

46DD in questions

What is 46DD in European sizing?

A 46DD corresponds to 105E in European sizing and 120E in French/Spanish sizing. The cup volume is identical — only the band numbering changes between systems.

Is 46DD 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 44DDD and 48D hold exactly the same volume as 46DD.

My 46DD doesn't fit — what should I try?

If the band rides up or feels loose, go to 44DDD. If the band digs in while the cup is fine, go to 48D. If the cup overflows, try one cup up in the same band; if it wrinkles empty, one cup down. Two minutes with the calculator confirms it.
