That's more of a Fad pattern. Certain kinda of items will be huge for awhile, generally cause of something pertaining to the outside world, like Pirate of the Caribbean, you could tell there was a huge want for pirate items after each of the movies came out. It's the same with futuristic things, alot of people will probably be wanting space suits and that kind of jazz since Ender's Game and Pacific Rim came out, two very popular futuristic movies coming out a few months apart are likely to start a fad like that.

Same can be said for Archery stuff now that the Hunger Games came out, along with crazy kinda of outfits, since the movies are very theatrical and do boast alot of heavily layered outfit with lavish designs.
