7 Sustainable Brands Making Plus-Size Clothing

Limited sizing remains one of the fashion industry's most persistent problems. Despite growing demand for inclusive sizing, the industry still treats smaller sizes as the norm. This bias was starkly evident during the fall/winter 2023 season—across all fashion weeks in New York, London, Paris, and Milan, nearly all 9000+ runway looks were shown in U.S. sizes 0 to 4. A mere 0.6 percent featured sizes 14 and above.

‍

While some fast fashion brands do offer extended sizing, they aren't suitable for sustainability-minded shoppers.

‍

Fortunately, more sustainable brands are embracing size inclusivity, recognizing that environmental responsibility and body diversity naturally complement each other.
