Mid-luxury is a term applied in the U.S. market to fashion, vehicles, hotels, apartments, and other consumer goods and services, for brands that are not as expensive as luxury goods, but more expensive than mass market brands.
As of 2018, Amazon U.S. has been struggling to get luxury brands to sell on its platform, but has had success with selling its house brands, such as Pinzon (sheets and other domestics) targeted at the mid-luxury market.
