World Cup

The World Cup comes around once every four years, and when it does the shirt is the story. Every host cycle sets off a wave of national-team kit drops, retro re-releases, and a trading-card run that outlives the tournament itself. This is the running ShopTwits record of what fans actually buy across each World Cup: which jerseys sell out, which cards heat up, and how the resale market moves from qualification to the final. Each staging gets its own section below, and the page stays put so the history compounds cycle over cycle.
