Was shopping in H&M and was looking through the basics range - needed leggings and t shirts etc. took some leggings to try on, an picked up a pair of medium without going it much thought, as I am a size 10-12. Luckily I did try them on because they were massive on me. When I went to look for a smaller size I noticed a sign saying they had 'revolutionised' their sizing for the basics range to allow for bigger sizing, which is fair enough.
But why mess around with all the rest of the sizes?! Why not just label it xxl rather than changing medium to fit a size that would have fit a 16-18.
And to make it all even more stupid, it was only their basics range that had changed, the rest of the stuff was still a normal size.
I ended up at the till with a stupid range of sizes, with some smalls, some mediums and one large for their stupidly small skinny jeans. An this is just one store.
