Hi. I had 275cc low profile overs many years ago, had a baby and they also lost upper pole, sagged and one bigger than the other just like you described!
I had mine redone yesterday and now have 500cc hp overs. Pockets were big enough so straight forward so far. I’m taller however at 5ft 9 and 10 stone 6, size 12, prev a small D. No idea what I’ll end up being now when they’ve settled but no bigger than a dd/e I suspect. They don’t look too big at all, but they’re all packed up in pre op bra so no pics yet x
