Rotation refers to the items someone actively wears, cycling through different pieces rather than wearing the same thing daily. 'Adding this to the rotation' means a new piece will be regularly worn; 'heavy in the rotation' indicates frequent wear. The concept reflects sneakerhead and streetwear culture's collection mentality—having enough pieces to rotate maintains novelty and preserves individual items from overwear. Rotation size varies by collector: some maintain small, curated rotations while others cycle through extensive collections. Discussing rotation is standard community conversation: 'what's in your rotation right now?' invites sharing current preferences. The term implies intentionality—rotation pieces are chosen, not just owned. Items can move in and out of rotation based on season, mood, or style evolution. Understanding rotation helps explain why collectors continue buying despite full closets—it's not about having enough, it's about having options.
