Ten changes that move an apparel product page.

Most product-page advice is written for gadgets. Clothing has a different problem: the shopper is not sure it will fit or suit them. Ten changes ranked by how much of that doubt each removes, with the ones that look important and are not.

2D photo swap or a real render? How to tell in thirty seconds.
