Life fashion ebbs and flows

I find it interesting how fashion ebbs and flows over time, but that there are also fashion cycles within out lives. Lets analyse cartoons for example. Hello kitts, barbie, etc is cool from ages 2-7, then we start to hide the fact that we love/play with them.

Then at the age of 13 or 14, for me when high school began, things from the early 1990's were once cool again, but in small doses, as one was never sure when it would become uncool. 

Towards 17 years of age this cool trend started to die out (for my schools at least). Now fashion icons, designers, and stores are trying to bring things like this back for my demographic.
