It all depends on the product I'm buying and the brand I'm buying from. At the moment I'm looking for sweatpants, I've never bought a pair of sweatpants that fit me correctly. I'm looking for something slim fitting with a tighter fitting ankle, so I like to see them modeled because I'd like to see just how slim they are. Same goes for denim, I'd like to see it on a model because I'm picky about my leg openings. For shirts (mainly tees) it doesn't really matter because they aren't as varied size wise, but it's still nice to have more pictures and whatnot. I'd say jackets is another one where it's more convenient as well, because with parkas some come longer than others, so it's nice to see just how long the parka is. Again, depends on your product.
