In my limited experience and limited knowledge yes for Zara and Topshop. H&M generally yes? H&M's current seasonal clothes seem to be trend sensitive. Then they also have other small collections -- work-wear (generally trend aware in shape and color, but not edgy), basics -- tees and knit mini skirts, jeans (includes some more classic styles, but nothing dated really), sleepwear, and the goth section -- trend sensitive in shape sometimes but ya know, all black and hardware-y. Goth is really pretty unchanging in it's basic look over time -- I'm thinking it might date even less than classic dressing. Has Hot Topic really changed much at all since I was in high school in the late 80's?
