Ready to Wear Definition presented by Apparel Search

Ready-to-wear or Pret-a-porter is the fashion design term for clothing marketed in a finished condition, in standard clothing sizes. Some fashion houses or fashion designers create ready-to-wear lines that are mass-produced and industrially manufactured. Others offer lines that are still very exclusive and produced only in limited numbers and only for a limited time. In contrast to haute couture, these lines are never one of a kind. High-end ready-to-wear lines are sometimes based upon a famous gown or pattern that is then duplicated to raise the designer's visibility level.
