I had JNCO and Zonz back in grade school (the 1991-1999 1st through 8th was my age group) and I'm glad the trend is to skinny stretch pants now. They work way better than the baggies of the 90s though I still have baggy and skinny outerwear.
Slouchies, or whatever they're called, look f'cking sweet ... I'm definitely going to adopt this trend so I can, as shredlife so eloquently stated, flag down other flamers in large groups of people.
The worst style, IMO, was the the boot cut AE/Abercrombie/Hollister/Gap etc. fad of 1999 through mid 2000's. At least they were low-rise so they didn't look completely goofy.
