If you do it, do you do it to fit in and be popular?

Like last week it was non-uniform day at my school, and 99% of the girls were wearing Hollister, Abercombie, jeggings and Uggs

and i dont get it! why would loads of people waste money on this expensive clothing for? i bet half of them don't even like it! they're so plain! It was so stupid to me, i bet half of them just wanted to fit in with the trend.

What do you think of teens wearing uggs and hollister and stuff???
