Clothing is one of the biggest categories in online retail and one of the most returned, and photos sit at the centre of both. A shopper who can't judge fit, fabric or colour from the images either doesn't buy or buys two sizes and sends one back.
A full set per style usually runs from a flat lay or ghost mannequin shot to on-model front, back and side views and a lifestyle image. Multiply that by sizes, colourways and drops each season, and clothing becomes the biggest production job a brand has.
