Isn't that problem self-solving? Who wants to dress like a celebrity dressed last season- you want what they're wearing this season. Keep it up to date, with what's "in" now.
I think the stock would run out much faster than fashion would change. Also, there are probably 4 or 5 retailers selling similar items; you want your affiliate links to spread the load over those sites so as not to kill any of them quickly.
Of course, all this assumes your site explodes and you help sell thousands of outfits per day; which sounds unlikely to programmers, but maybe not for the people who buy all those awful magazines that are more popular than Linux Voice.
Yeah, stock turnover is much higher than trend duration. Any retailer that knowingly let stock last longer than trends would be burning their margin.
Stock is measured in weeks or months but trends can last for years, and recur, and recur, and there's no value in an affiliate link to an out of stock product.
