Plus-size model is term applied to an individual of average to larger stature (sometimes but not exclusively overweight or obese) who is engaged primarily in modeling plus-size clothing. Plus-size models also engage in work that is not strictly related to selling large-sized clothing, e.g., and advertising photography for cosmetics, household and pharmaceutical products and sunglasses, footwear and watches. Therefore, plus-size models do not exclusively wear garments marketed as plus-size clothing. This is especially true when participating in fashion editorials for mainstream fashion magazines.
Synonymous and interchangeable with plus-size model is "full-figured model", "extended-sizes model", and "outsize model". Previously, the term "large size model" was also frequently used.
Fashion designers are starting to look more closely at the earning potential from plus-size clothing, and have used plus-size models for their advertising campaigns and catwalks. Jean-Paul Gaultier and John Galliano both used plus-size models in their Spring 2006 showings in Paris. Gaultier also used plus-size models Marquita Pring and Crystal Renn in his Spring 2011 Ready to Wear show. Italian plus-size fashion house Elena Mirò now regularly stages biannual prêt-à-porter shows during Fashion Week in Milan. Mark Fast and William Tempest each used plus-size models during their own London Fashion Week showings for Spring 2009, and again as part of All Walks Beyond the Catwalk event held on 19 September 2009 in association with the British Fashion Council. Mark Fast also used plus-size models in Fall 2010, Fall 2011, and Spring 2012.
Lane Bryant began trading in the early 1900s as a producer of clothing for "Expectant Mothers and Newborn"'. By the early 1920s, Lane Bryant started selling clothing under the category 'For the Stout Women', which ranged between a 38–56 inch bustline. The earliest catalogs used illustrations to sell their products, but by the mid-1950s photographs were integrated into the catalogs as the evolution of printing technology made this option available. After a hiatus through the 1960–1980 period, Lane Bryant again began using plus-size models.
