Today's Polyvore set was a contest set for a boot company, called SOREL, themed on Winter Style.
I used some winter sport photos, snowshoes and a pretty tinted photo of a model in winter attire.
I didn't win. When I look at the winners selected by these various companies I often think that, after looking through a 1000 sets, it ultimately came down to "eeny-meeny-miny-mo."
And "mo" isn't always that impressive, but perhaps that's just the view of a graphic artist; not a fashion marketeer.
