This label tends to give sellers the most trouble, as it is widely used as a descriptor for items manufactured in the 1950s. This is a bit misleading, as those items can also be qualified as vintage. To be safe, ecommerce merchants should only apply the word retro to items that are merely inspired by past designs. If a chair was built in 2015, but has the look of and was modeled after popular chairs of the 1950s, it can be labeled retro. In addition, retro can be used to describe pieces that are in fact aged, but not old enough to fall into the vintage or antique categories. For instance, a chair from the 1990s with design elements distinctive of that era could be called retro. It’s a little bit old, a little bit new, but not from last season’s collections.
