I've measured as per the boob or bust method and have got the 32GG result. I'm currently wearing a 38GG and I've noticed my only under wired soft bra is 36G. I also have a 36GG and my padded bra is also 36GG. That fit beautifully when I bought it but isn't comfortable after hours now.
I can't remember which order the bras were bought in but since all were bought I've lost 1.5 stones.
I know 100% that a 32 would be too right for me. I have asthma and a damaged back and can't cope with tight things. As we all know M&S is rubbish and been mean to me before could anyone please help give me more guidance? The only shops I'll be able to try are M&S, Sainsbury's and M&Co (though they don't go bigger) and TKMaxx but that's hit and miss if you're over a 34.
