Doesn't the fitter make a difference?! When I was fitted a couple of months ago I was told I was a 34GG and came home with a lovely selection of bras that ended up going back as they were too small and I went back to my old size of 34H.
I went again on Sunday and the fitter seemed so much more interested in finding what I wanted. I ended up buying the Purity moulded bra )which I hate as it sort of flattens me but I need a moulded bra and it's the only one that fits) and this Bloomsbury which I am completely in love with (sad I know!). I which Bravissimo made nude bras in the same shape as this as it fits so well!
What I am trying to say in a very long winded way is, regardless of which shop it is, if you aren't happy or comfortable have another fitting whether it's Bravissimo or any other shop. I've given up so many times but bras are so expensive I was determined to get it right this time!
