Please forgive this, I promise you that I am not some old horrible stalker looking at young girls. The fact is that the girl went to college in fashion design and looking at clothes is second nature to me.
Anyway, I went to a college football game here in Florida last weekend. The fashion trend among the college girls? Lots of what you are saying: Short, tight-fitting, and many designed so you can't tell if they have a crotch or not. Long-legs are important, even if only an illusion. I say this to agree with you.
What surprised me was the way some girls wore them with their camel toes visible, purposefully. Riding in their butt-cracks was common. These were expensive clothes on college girls who obviously were aware. On the beach, and in associated bars, stores, etc, they were wearing thong bikinis unapologetically.
I say this only as an observation, but tastes have evolved once again. They are running out of places to delete fabric, as far as I can tell.
Thanks for writing, it was a fun read.
