Styles, at least for women and girls, have changed signficantly this season. No more low, low cut jeans with a thong hanging out, no more belly shirts, etc. It's nice. Actually now t-shirts are cut much longer and mini-skirts are worn with tights or leggings (UGH!) under them. It's a nice change from the past few seasons.
Funny, many girls here in WV haven't picked up on it and still wear belly shirts, low, low riders, and bare mini-skirts. It's funny because they strut around thinking they're hot stuff, when in fact, they're just completely out of touch with what's in style, and more important, what's appropriate.
I've noticed a big change in girls' clothing in my area (western New York), also. I'm now seeing many, many tastefully dressed teenagers.
