How they generally work is they steal genuine pictures of clothing so it looks convincing. But then they just knock something together when you order it, using vastly inferior materials, that may or may not fit or even resemble the item you ordered.

Also, read the delivery/return info pages and see if there’s a return address provided. Genuine retailers that sell at high volume and low price (e.g. boohoo, NastyGal) will have their address available. Knock off sites hide theirs to disguise the fact they’re in Hong Kong, so may only provide an email address.
