backpacks are awesome, provided they're waterproof. I thought the old suede daypacks looked great, but weren't practical for those living in rainy climates. Knits would be cool, or maybe pants made of interesting materials that are less dressy than the current ones on offer.
I don't think those pants are meant to be worn high waisted, most of the Damir/Silent pants seem to have this drop crotch thing going on that looks better if you don't hike them up. Like shah said, it's probably best to look at other brands if that isn't the aesthetic you're looking for.
