Okay kiddo, so have you ever heard of someone who can tell you what kind of clothes or toys are going to be popular next year? That’s basically what WGSN does, but for big companies that make clothes and other stuff for lots of people to buy.
They look at lots of different things, like what colors people are wearing, what kinds of designs are showing up in magazines, and what famous people are wearing. They use all this information to predict what kinds of things people are going to want to wear or buy next year.
Then they tell the big companies who make clothes or other things so they have plenty of time to make them and get them in stores. It’s like magic, but with a lot of research and hard work!
