Thrift shopping is one of the best ways to build a wardrobe — better prices, unique pieces, and a lighter environmental footprint. But it comes with a problem that new-clothing shoppers rarely face: the care label might be faded, missing, in another language, or from a labeling era that predates the symbols we use today.

Here's how to figure out how to care for thrift finds, whatever state the label is in.

Why Thrift Labels Are Harder to Read

Thrift finds come with a few label challenges that new clothing doesn't:

International Label Systems

Most of the world uses the ISO 3758 system, which relies on graphical symbols and temperatures in Celsius. The US and Canada use ASTM D5489, which combines symbols with text and expresses temperature in Fahrenheit. If you find a garment with a label that uses dots instead of text temperatures, that's the ISO system: one dot means low heat, two dots medium, three dots high.

Common text you'll see on non-English labels and what it means:

Vintage Labels: Before the Symbols

Care labeling wasn't legally required in the United States until 1972 (FTC Care Labeling Rule). Garments made before that may have no label at all, or a label with text-only instructions using older terminology.

Common vintage label phrases:

Pre-1972 garments from Europe may have labels in the local language with no symbols. Use the translation guide above or, if the label is illegible, default to the fabric rule below.

When the Label Is Gone or Unreadable

If there's no usable label, the fiber content is your best guide. Most fabrics follow predictable rules:

If you can't identify the fiber by label, do a burn test on a loose thread from an inconspicuous seam. Cotton and linen burn cleanly with a paper-like smell. Wool smells like burning hair and self-extinguishes. Synthetic fibers melt and bead. Silk burns slowly with a hair-like smell and crushes to a fine ash. This isn't foolproof but it narrows things down quickly.

A Practical Rule for Unknown Vintage Pieces

When in doubt about any garment with an unknown or illegible label:

  1. Hand wash in cold water with a small amount of mild detergent
  2. Gently press (don't wring) and roll in a towel to remove excess water
  3. Lay flat to dry in its natural shape

This approach is safe for almost every fiber type. It's slower than machine washing, but it won't ruin a piece you paid good money for.
