Hi I have the same problem & #1 I used to find the demi cup underwire bras once & a while worked much better than regular. But now instead of the wires being a true U shape they seem to have an elongated bottom & thats when the wire started going under my arm pit even with a 2 hook bra I used to be a 34 / 36 DD Im not fat but have bigger boobs Im abt 5 ft tall and considered petite with regard to bone structure. so now I look for a true U shaped demi which I think demi means shorter ends on the wire? not east to find when i need the middle part to be so close - so if I find one close to fitting I buy it & sew the middle closer together. Good luck I know it is always a struggle - even if I don't need a bra at the time if I see one that is close I buy it. and honestly do not buy online - always have to try it on..
