too old

I bought new jeans the other week. They are pretty trendy. I'm worried that they might be a little too trendy. They're quite flarey, y'know. Young looking. Perhaps indeed too trendy. I'm worried that I might be too old for some of my clothes. The guy in the shop said, "Yes, physically they do seem to fit you." It's easier for children. Their clothes have age ranges on them. I think they should continue that. If I pick up a trendy tracksuit top or something, it can have on it 22-29 or something, and I'll know to move on to the cardigan rail instead.
