ITA, it's awful and yes I do feel the brands are targeting girls and boys younger and younger. It does the brands no favours and it's all led by trying to please shareholders. Nothing to do with sustainable fashion either environmentally or economically. Companies should think about longterm goals not just about this year's sales figures.
I was interested in fashion from a very young age and I did ask for things like Trussardi key chains and Loewe belts and was bought some very nice small Italian brand bags as gifts, but I didn't buy myself or even think about designer goods till I was in my late-teens/early twenties.
I think it is a bit counter productive, if I see teens with certain items, it actually stops me from buying them.
