Hello darlings! I know I don't post here a lot anymore nowadays but I hope some of you remember me

Anyway I'm writing my bachelor thesis about music and fashion in the young women's subcultures of Tokyo / Shibuya. And I basically need one (or more) articles to prove that Ayu really is a fashion trend setter as I claim her to be.
For example I remember reading an article of her endorsing a certain lipstick that sold like half a million copies on its opening day, but I can't find it. Does anyone remember this and know where to find it? Any article is fine as long as it's about an endorsement she did or something she wore that went on to sell a lot or become popular.
I will keep searching myself but all help is appreciated!
