Nothing's more "American Summer" than a pair of cut-off blue jeans.
I've also always had a thing for denim skirts. In college, a girl in a denim skirt, white blouse, and red shoes would grab my involuntary attention in a heartbeat.
Recently, a new trend which combines these two favorites of mine has really gotten popular, and I must say, I approve. It adds a little edge to a classic look, and a little class to an edgy look. During rush this year there was a whole sorrority full of girls in t-shirts and cut-off jean skirts. That's when I knew it had arrived. I can't say I'm disappointed.
