@Stuffragette
Thank you so much for your replies. She was measured in rigby and peller because she absolutely refused to be touched by a tape measure.
I have ordered a selection of bras from all your suggestions. I think a sports bra might be the answer. I have never heard of a minimiser bra. I will investigate.
She's only 5,2. And a size 10. She definitely hasn't grown into her body if that makes sense. She's still a little bit squishy. But she's delicious and I love her and feel so sad seeing her hunched over, partly by the weight and partly as she's so self conscious. Poor DD.
Do you know what bra/brand r&p fitted her in to get the i cup?
This could make a really big difference to what she needs in other brands. A quick look on r&p suggests their 32i bras are all primadonna, which misses out all of the double letters. If that's correct it means she's a good bit smaller in most uk brands
Prima donna goes A, B,C,D,E,F,G,H,I (so she's the 9th size)
Freya, Panache, Curvy Kate, Bravissimo etc all go A, B, C, D, DD, E, F, FF, G, GG, H, HH, J JJ and so on.
That would, by my reckoning, make her closer to a 32G in uk bras which opens up the options quite a lot.
Bravissimo have a much better non wired selection these days. I've got thr Zara, flora and fern (and I'm bigger than your DD) and liked them.
For sports the panache underwired is the bomb, nothing moves in that thing
