Well, yes, I have been scammed with a fake order that appeared to be from a widely known international department store for my graduate collection. It turned out that the people were impersonating existing industry profiles, acting as buyers, production facilities, and the store itself by using various profiles. They even sent first production samples of the garments finished to detail by my instructions. I was suspicious from the beginning but even my industry contacts, who had been in the business for years, believed the order to be real after seeing the contracts.
I later found out that it was an extremely elaborate fraud with the help of London College of Fashion, as they had put me in contact with the Department of Trade UK to even further my opportunities in the international market. At this point, we all realised that the order was not actually coming from the real department store after checking with their teams.
