International regulations about Accessibility and Design for All are clear. They provide two guidelines to ensure equality, autonomy, and non-discrimination, such as Reasonable Accommodation and Universal Design (or Design for All). Reasonable Accommodation leads to Adapted Fashion, which adjusts clothing to the body (average clothes for the average consumer). Universal Design leads to Inclusive Fashion, which creates clothes for everybody even if you have a body issue. Design for All (or Universal Design) implies projecting from the beginning to the end of the design process based on inclusion. In this context, the Museum-Foundation Juan March in Palma was the starting point to conceive, develop and communicate a collaborative and transdisciplinary design project; it was designed under the principle of Universal Design. This transdisciplinary co-design project took place during the first semester of the 2019–2020 academic year with a third-year BA in Fashion Design students. They designed an inclusive ready-to-wear fashion micro-collection, which focused on sensitizing BA in Fashion Design students, promoting a change of attitude, and fostering a better understanding of the challenges clothing design process. Students were invited to complete two online questionnaires to collect data on the project. The first survey was used to assess alumni’s perception of acquisition, development, and/or consolidation of key competences in participating students and control groups. The second survey was used to assess alumni’s activity on the project among participating students. This project was aimed at sensitizing BA in Fashion Design students, promoting a change of attitude, and a better understanding of the challenges clothing design process. After visiting the museum, getting inspired by their artists and their works of art, creating a mood board, and drawing the first sketches, two groups were created to develop an inclusive, ready-to-wear fashion micro-collection. Each collection focused on a different users’ profile: one group worked with a model with achondroplasia (woman), and the other group worked with two wheelchair models (man, woman). Despite the mixed results, the main objectives of the project were reached. As members of a school community, students must learn about other realities that differ from their everyday environment. As members of a school of design, students must be aware of an important prospective market niche and expand their fields of action that must include Design for All. In any case, human diversity is the key concept to approach user-centred design in the twenty-first century.
