What term is commonly used for clothing that is primarily sold by one retailer and not available elsewhere?

The term "private label" refers to products that are manufactured by one company but sold under a retailer's brand name, allowing the retailer to offer unique items that cannot be found at other stores. This strategy enhances brand loyalty and encourages customers to shop specifically with that retailer for exclusive products. Retailers often use private label clothing to differentiate themselves in a competitive market, catering to consumer preferences for unique or specialized apparel.

While "exclusive line" might seem similar, it doesn't always guarantee that the products are private label. It could refer to clothing lines that are exclusive but still branded. "Branded clothing" typically means items that feature an established brand's logo or label and are sold through various retailers. "Designer label" refers to clothing from high-end designers, which may be widely available or sold through multiple channels. Therefore, "private label" is the most appropriate term for clothing specifically sold by one retailer.
