A dress, an embroidered cloth, a uniform of fabric: light eats the color, moths eat the yarn, a thin hanger cuts the shoulder in two within a year. In the overview Security for collectors textile is a matter of climate, not a small compartment in a certified safe.
What gets ruined without a thief
Light, dust, acid from cheap hangers and from cardboard, moths, a basement that smells musty. You store in the dark, in covers that breathe, flat when the piece is heavy, on a rail only when the shoulder can take that over time. Moth product does not go directly on the fiber. You check twice a year whether something is eating.
When someone comes
Bulky, of no interest to many offenders, irreplaceable for you. The cabinet with the couture is locked, not the first door in the hall, and it is not a damp steel safe. Furs are a text of their own, because moth and the law sit even tighter there: Furs.
The folder
What it is, size, material, damage already there, provenance, receipt. A photo from the front and of the inside with the label. The policy, one by one, when the price calls for it.
