Why does this keep being referenced as a thing?
When did adult women start taking style tips from teenagers? I occasionally ask my teen daughter, 'Which jacket?', but that's because she's into clothes as I am and I want her to feel involved. I'm not actually going to take her advice. She's 14, she knows about teen-fashion, which is great, but it's not really my desired reference-point.
And it's not about age, I certainly don't put an age -limit on any item of clothing, but I'm also not interested in what style of jeans of trainers teens are currently wearing. High fashion certainly isn't for teens, it's middle-aged and above women that have serious cash to spend on clothes, not 15 year-olds.
Teens want to blend in, they desire to ultimately conform with other teens. It's older women who have the confidence to be interesting with their style.
So why is anyone interested in what teens are wearing?
