petite size strapless bras

[runner2]

DD needs a strapless bra to wear under her dress for her upcoming school prom, but is struggling to find one in 32AA on the high street. We really don't want to be paying more than £20 for one. Can anyone advise please?

First things first, have you measured her following this guide?

Someone who is genuinely a 32AA would have an under bust and over bust measurement of 32" meaning that they were flat chested (and probably wouldn't need a bra except for nipple coverage!).

She's just reminded me her first bras were 32AA but the ones she's wearing at the mo are 30A! She is flat-chested but that's kind of the point - she wants a padded bra to give her shape but it needs to be strapless.
