well i did it!
i went and got messured at lunch time, not once but twice! and im still none the wiser as to what size bra's to buy!
ive been wearing 40DD for years
but
marks and sparks said i was 46E
(thats a huge back size)
and debnhams said i was a 42/44DD maybe E but she very much doubted it.
so dunno wot to do now lol
