How should I store a dress between wears?

The answer

Clean it first, because stains that seem invisible can darken over time, then keep it in a cool, dry, dark place in a breathable garment bag. Use padded or wide hangers for sturdy dresses and fold delicate, heavy or bias-cut ones, ideally with acid-free tissue. Avoid plastic bags for long-term storage because they trap moisture. Check stored dresses now and then for moisture and pests.
