Sister sizes of 46A

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

44B

This is one of the easiest profiles to shop: nearly every brand carries it. Your bigger risk is fit quality rather than availability — 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.

Who makes 46A? 97 of the 632 brands in the Cherry Size catalogue are confirmed to carry 46A 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.

46A in questions

What is 46A in European sizing?

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

Is 46A big or small?

It is a common band with a shallower cup — widely stocked and easy to find. Cup letters mean nothing alone: a cup only has a volume relative to its band, which is why 44B and 48AA hold exactly the same volume as 46A.

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

If the band rides up or feels loose, go to 44B. If the band digs in while the cup is fine, go to 48AA. 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.
