I’m from notts and would prob say the obvious places, debenhams and m&s. There’s la senza too. Deffo go to a couple though as they might measure you different and its nice to be able to try the different sizes on to see which feels more comfy. Like you, I had my nipples stitched too and when I was measured, I found them a bit sore in a bra at first. But it’s all good now xx
