Event t-shirts are unforgiving. Unlike corporate apparel programs where you can reorder if something is off, event shirts have a hard deadline — the event — and a hard quantity — the registrant list. Getting the order wrong means either scrambling for a last-minute reprint or handing out shirts that do not match the event branding. At Champ ESP, we have built our event apparel process around these constraints. We require artwork approval two weeks before delivery, use production proofs on first-run designs, and build a small overage into every event order to cover late additions and size surprises.
