Coats. Clean all storage items first, because food stains attract moths and lingering oils from perfumes can discolor fabric. Hang structured or down coats on wooden hangers in breathable canvas garment bags (plastic bags trap moisture and can yellow fabric). Polyfill-stuffed coats can be stored in compressed, vacuum-seal bags.
Sweaters. Fold and stack sweaters in a plastic bin; separate the layers with white tissue paper if color transfer is a concern.
Footwear. Clean the soles of winter shoes with a wire brush and the rest with a shoe brush. Sprinkle baking soda inside and insert shoe trees. Boot legs should be stuffed with tissue and the boots stored upright.
Accessories. Roll up scarves before storing them loosely in a plastic bin with gloves and soft hats. Shaped hats should be stuffed with tissue paper and stored in hatboxes.
