On-model beats flat-lay for identity goods
For a generic apparel store a clean flat-lay is often the most efficient product image. Merch inverts that. Your buyer is picturing themselves in it, around other people, and a garment laid flat on white gives them nothing to picture. On-model shots in a plausible setting do that imaginative work for them, without the location, the people and the shoot day merch photography used to need.
