Fashion is always (at least) 6 months ahead. We're still dressing for the current winter while the new F/W collections are being showed on the runways in the fashion capitals. When I worked as a model this meant shooting winterstuff in the boiling summer heat and summerstuff, when the client didn't have a budget to fly somewhere hot, on a freezing beach somewhere in Europe. The model had to stand it and shut up. Once in Arizona, all bundled up in wool winter stuff,  with a fresh 40 degrees C (!) I fainted. They threw some water in my face, had me rest for 5 minutes and then I was on it again...
