Collecting jerseys is mostly about slowing down damage. Light, moisture, and pressure do the damage; a few habits prevent most of it.
Light is the slow killer
Direct sun fades dyes and yellows white fabric. Store jerseys in a closet or a closed cabinet rather than on an open wall. If you display one, use a frame with UV-filtering glass and keep it out of direct sun.
Humidity and airflow
Synthetic fabric tolerates humidity better than cotton, but trapped moisture still causes odour and mildew. Keep the storage space dry and avoid sealing a jersey in a plastic bag while it is even slightly damp.
Hangers versus folding
Wide wooden or padded hangers support the shoulders without stretching the neckline. Thin wire hangers leave shoulder points over time. For stitched jerseys, folding flat with acid-free tissue between layers is often safer than hanging.
Tags and provenance
Keep the hang tag, the receipt, and any authentication paperwork with the jersey. Provenance is most of the resale value, and it is easy to lose and impossible to recreate.
Do not laminate or vacuum-seal
Vacuum sealing crushes patches and traps residual moisture. Lamination is worse. A breathable garment bag in a dark, dry space is the practical answer.
