Bra advice please!! Petite rib age, narrow shoulders, high placed HH boobs, which bra? Any recommendations?

[LaJoconde]

Please help, I’m short, so not much rib cage from top to bottom, or around, with large heavy boobs, narrow shoulders

every underwire bra I’ve tried jabs me in the underarm, falls off my shoulders, or I feel like I’m being suffocated.

ive done the measuring thing and am a 34 HH

but my boobs have lost volume on top, and now they hang down looking rather sad. They seem to have shifted outwards as well, and I think the ligaments have stretched beyond their elastic limit.
they’re huge and heavy and need support, but I have narrow shoulders so most bras just keep falling down. Sports bras just crush the boobs together in a sweaty uniboob shelf, which is very unflattering, and hot.

am I asking for the holy grail, or has any heavily endowed shorthouse like me found a bra that’s comfy?

I just buy direct from the Polish site. Their band sizing is not generous like some uK brands, so you may find you need to go up a size. Somehow the bras are just more flattering on me than UK brands, they don’t do the East West thing that I get with Fantasie, or sit halfway round my back, or up into my armpits. Everything is held more up front. They grade their wires differently and that makes the cups fit better with smaller back sizes.
With Ewa Michalak the pants are true to size. With Comexim they come up small and you need to size up at least one size. Ewa M and is easier to start with anyway as the cup sizes are comparable. With Comexim and Avocado you need to count what you are from a D cup as they don’t do the double sizes , so a UK GG is a Polish J.

I'd second the Ewa recommendation

I'm a 30j, lost upper fullness and naturally very close set. Recent uk successes - panache Ana plunge, bravissimo Scarlett (millie is same cut I think), panache envy

5 ft 2 34 H here. Primary Donna Deauville. It’s the only one I wear. Spendy but worth every penny. If you’ve self measured though I’d have a fitting at Rigby and Peller or a good independent bra shop to make sure that is the right size. If you’re really petite you may well be narrower than 34. I’m a 14/16 dress size. It’s honestly life changing though.
