Argggghhhhhh!
I haven't been in there before and therefore don't know how the "system" works.
One hour and 45 minutes later with 4-5 different girls telling me the back was too big or too small cup too big too small too full too cutaway one felt the need to enlighten me.
It turns out that when you get there you book a fitting and then you have one girl who helps out and you have a chance of getting the right bra.
Along with this suggestion she also told me that I was too late now but I could come back another day.
So no new bra, norks still firmly in waistband
Also felt it was a complete embarrassing waste of time and effort
