Often when you go and see a movie you’ll find mannequins dressed up as characters from the movie standing alongside the posters or sometimes several as a complete display of their own. And the kids love them – mine go up and walk around them and talk about the way they’re standing and what they’re wearing.
So based on what I see at the movies, if you’re promoting to kids, it makes sense to me to do similar things with the mannequins in a normal store. Find out what current movies kids are interested in and dress up some mannequins in similar styles. Place them with the other clothes you’re selling. And read a bit more about testing in shop mannequins.
