I'm a size 9 in British sizing which is annoying. A ten is just a bit too loose for me and an 8 is just a bit too tight. Obviously that's variable depending on where I shop for clothes but generally I'm a 9 in my chosen outlets. Fortunately I'm a good seamstress.
Last week I went to a friend who is in her late 40s. She told me that sizes have changed and in fact a size 10 now would of been a size 12 back in the 80s-90s. She went and got some vintage clothes out of her wardrobe that were English branded and size 10. I tried them on but all of them were too tight.
I decided to research this but it didn't take me long to discover that in the last 40 years a size 10 has grown by a whopping 10 centimetres.
In old money I'm not a size 9 at all, I'm a size 11
