I recently tried this. I like quite a lot of kids clothes and am a size 10, so theoretically the measurements often match up for circa age 14-15. But the item (a jumper) just didn't sit right. I can't put my finger on what it was though!
So my question is, are older kids clothes cut differently to the equivalent adult size? Waist and chest measurements match, but are perhaps the shoulders cut narrower, or less room for breasts, or something?
I want to know whether it's worth trying again and ordering some more things!
