What are some examples of fads?

Many girls are so into all the Skinny Jeans like Miley & Max clothing line. Girls are into tank tops, mini skirts, straight hair, and those HUGE FLOWERS in their hair that are so ugly. I mean they are so ugly and galdy! But anywho- they also like ugg boots, knee high boots.. oh and also the most popular brands like Aeropostal, Holloster, American Eagle, Abrocrombie and Fitch. Plus Vera Bradley purses, handbags, and wallets.

Boys on the other hand love Vans shoes, cowboy boots, steel toed boots, and all the popular brands like the girls.
