i had 300/320 mod plus unders 🙂 made me go up 2/3 bra sizes depending where i shop so i am really happy! her judgement is pretty good, i haven’t seen any complaints about her on here and it seems a lot more girls are using her in the last couple of months, i would trust her judgement and you can always ask for a couple of sizes to be ordered and make a decision on the day, i had 3 different sizes ordered x
