Vintage clothing can be worth far more than modern pieces, but it takes a trained eye to tell the difference. These clues will help you date garments quickly.

Check the Label

  • Union labels: The ILGWU union label was used on many American garments from about 1900 to 1995. Label design changed over the decades, which helps with dating.
  • Care labels: Required in the US starting in the early 1970s. A garment with no care label may be older.
  • Made in USA: Much American clothing production moved overseas in the 1980s and 1990s, so older pieces are more often US made.
  • Sizing: Vintage sizes run small compared to modern sizing.

Look at the Zipper

  • Metal zippers were standard until plastic zippers became common in the 1960s and 1970s.
  • Side zippers on dresses and skirts are typical of mid century clothing.
  • Brand names stamped on zipper pulls, such as Talon, often indicate older pieces.

Examine the Seams

  • Pinked seams (zigzag cut edges) are common on older, home sewn, or high quality garments.
  • Serged edges became standard in mass production later.
  • Hand stitching on hems suggests quality or age.

Feel the Fabric

Natural fibers such as wool, silk, rayon, and cotton dominate older clothing. Polyester double knit is a strong signal of the 1970s.

Consider the Style

Silhouettes change with each decade: nipped waists and full skirts in the 1950s, shift dresses in the 1960s, flared pants in the 1970s, and big shoulders in the 1980s.

Where to Find Vintage

Estate sales, church rummage sales, and small independent thrift shops often have more vintage than large chains.

Once you learn these clues, you will start spotting treasures that other shoppers pass by.
