Loved once, coveted again.
Pre-owned
A piece someone has owned before: bought new, then sold on. It may have been carried for years or never worn at all. The word only tells you someone owned it; for how it was used, look at its condition.
Preloved
The same thing in a warmer word; resellers use the two interchangeably.
Vintage
Pre-owned, and older. There is no fixed rule. Twenty years or more is the usual line, though some sellers use the word for younger pieces. A twenty-year-old bag can still be in excellent condition.
New
Never owned by anyone. A piece can be unworn, even with its tags, and still be pre-owned if a customer has bought it before.
Condition
Resellers grade condition on their own scales, usually from new and pristine through excellent and very good down to shows wear, and price a piece by its grade.
At reCOVET
Boxes hold pre-owned, vintage and new pieces, sourced from established luxury resellers and retailers and from the makers’ own boutiques. Each piece has a recorded condition, and its fair market value is the price for a piece in that condition. Every piece is authenticated by a third party before it ships.
