In recent fashion seasons, a concerning trend has emerged: a noticeable decline in the representation of mid and plus-size models on global runways. While some major fashion houses, such as Balenciaga and Givenchy, have sporadically featured larger models, these moments of inclusivity are becoming less frequent. This trend suggests a potential backslide in the industry's commitment to showcasing diverse body types, raising questions about the future of size inclusivity in high fashion.

Analysis of the Fall/Winter 2026 collections, encompassing 7,817 looks across 182 shows and presentations, reveals a stark reality. A vast majority, 97.6%, comprised straight-size looks (US 0-4), with mid-size (US 6-12) constituting only 2.1%, and plus-size (US 14+) a mere 0.3%. This represents a slight decrease compared to the previous season, where straight-size looks were 97.1% and plus-size was 0.9%. The current plus-size representation has regressed to levels not seen since Fall/Winter 2025, marking the lowest point since Vogue Business began tracking size inclusivity three years ago.

The geographical breakdown further underscores this issue. New York Fashion Week saw 97.7% straight-size looks, 1.9% mid-size, and 0.4% plus-size. In Milan, these figures were 97.3% straight-size, 2.6% mid-size, and a minimal 0.1% plus-size. Paris exhibited the lowest inclusivity, with 99.5% straight-size, 0.4% mid-size, and 0.1% plus-size, a significant reduction from previous seasons. London, however, maintained its position as the most size-inclusive city, with 92.7% straight-size, 6.5% mid-size, and 0.8% plus-size, largely due to designers like Karoline Vitto.

A significant disconnect exists between runway representation and the actual availability of sizes for consumers. A Vogue Business survey highlighted that 48% of consumers feel pressured to lose weight to be fashionable, with 63% citing sizing challenges in stores as the primary cause, rather than runway shows (36%) or campaigns (35%). High-end brands particularly struggle, as 27% of plus-size respondents reported rarely finding their size among luxury labels. Christian Siriano, a designer known for inclusivity, emphasizes that authentic commitment requires both runway visibility and real-world production. Influencer Remi Bader has also voiced frustration over brands featuring plus-size models but failing to offer those sizes for purchase, leading to consumer disappointment.

Addressing the plus-size consumer market requires more than just token gestures. While core sizes typically dominate sales due to greater availability, there is substantial untapped demand for extended sizes. Extended sizes often sell out quickly, indicating a supply issue rather than a lack of consumer interest. Brands need to actively engage with plus-size consumers through targeted marketing and genuine product development. Building trust and loyalty with this demographic, which has historically been excluded from luxury fashion, takes time and consistent effort.

The financial implications of expanding size ranges are considerable, involving investments in pattern-making, grading, sampling, production, inventory, and marketing. Designers like Christian Siriano advocate for approaching extended sizing with the same level of care and design as standard sizes, ensuring clothes fit well and feel good. Karoline Vitto incorporates adjustable elements and modular garments to increase versatility and reduce production complexity, making inclusivity more sustainable for smaller brands. Collaborations with high street retailers, such as Vitto's partnership with Pull&Bear, can also provide a pathway to scaling extended sizing, though such initiatives demand significant developmental effort.

The fashion industry's progress towards true size inclusivity remains inconsistent. While there have been sporadic efforts, the overall trend points to a regression rather than sustained advancement. Achieving genuine inclusivity requires a fundamental shift in both operational practices and creative vision. Brands must move beyond mere visibility on the runway and commit to the challenging yet rewarding work of integrating extended sizing throughout their entire business model. Only then can they consistently serve the diverse audience of women who have always been part of the fashion landscape, fostering authentic progress rather than fleeting trends.
