Clothes sizes drive me mad. I have size 14 jeans I wore to do the gardening this afternoon, which I bought when I was in 6th form (20+years ago) which still fit fine.
I also have size 10 Next Jeans bought more recently and am usually 8 or 10, but 12 if it's something fitted around the thighs, in M&S. So what do I need in FatFace?
