I certainly don't look at what is on the runways or in the stores year to year and take those ideas to my tailor. Occasionally, I may happen to see something I like, and copy or emulate that with through a custom made garment, but it's not something I seek out.
People see what's around them, good or bad, and react accordingly. I devour trade and popular magazines, and talk to lots of high end retailers and some designers, so my environment is different than yours. You probably just register some image on the street, in a restaurant, whatever, and store it subconsciously. Nevertheless, we are both affected.
