Three months ago, I hit rock bottom in the John Lewis fitting room in Oxford Street.
I'd gone in with hope. Again. Armed with a professional bra fitting (£30, thank you very much) and three "perfectly sized" bras in my "correct" size of 36DD.
Twenty minutes later, I was sitting on that little bench in the cubicle, nearly in tears, holding three bras that didn't fit despite being exactly the size I'd been measured for.
One was so tight I couldn't breathe. One gaped at the top like I was a teenage boy playing dress-up. The third, a £95 "luxury comfort" option, gave me back fat rolls I didn't even know I had.
The shop assistant knocked on the door: "How are we getting on in there?"
"Fine!" I lied, buying the least awful option because I was too embarrassed to admit that nothing worked. Again.
Sound familiar? Here's the shocking truth: 8 out of 10 women are wearing the wrong bra size, not because they've been measured incorrectly, but because the sizing system itself is completely broken.
