I went to M&S (yes, ok, so that was probably my first mistake) and asked for a pretty, non-wired 34A bra. I was hoping i might find something like this but somehow ended up with this.
MY DP said it looks like a mattress cover. 
"An A will be way too small for you" said the sales assistant when she first saw me. Lo and behold, the 34A doesn't even fit, it's too big! "That's all we have to offer, you'll grow into it" she said. 
What is wrong with British lingerie companies? An A fits me in France. I'm sick of UK bra sizes all being supersized and quite frankly rubbish. I just want a pretty bra that fits. Is that too much to ask? Who in their right mind is making bras out of mattress covers?!
