GLOCALIZATION refers to the local-global context: act locally but think globally and is getting more actual in the era of overconsumption. FAST FASHION is a really good example of overproduction and -consumption. FAST FASHION is nowadays dominating our western society. The wardrobes have been filled up with cheap clothes, which can be purchased anywhere, typically in bad quality, and they become obsolete quickly. Extensive marketing campaigns of huge fashion chains, cheap clothes and constantly changing collections attract especially young adults and make them believe that they need new clothes to feel integrated socially, to feel hip or even to feel more sexy. Gen Y and Z prefer fast fashion because of its low price.The negative environmental and social impacts are outstanding: fast fashion is really environmental polluting, and child labor is employed in this industry. People with higher intercultural sensitivity will become more confident global citizens, since their understanding of cultural difference becomes more sophisticated. All these cultivate the need to educate the youth. It appears among the Sustainable Development Goals (SDG4.7, 12.8. and 13.3). The EU launched a new circular economy action plan in 2020 emphasizing the role of textiles. The EU Youth Strategy also emphasizes the Sustainable Green Europe. All these show that fast fashion questions must be handled. The Fast Art – Slow Fashion project puts fast fashion into the context of the triad of sustainable development (environment, society, economy). Thus, the Fast Art – Slow Fashion project aims to cultivate awareness of the youngsters about the contribution of fashion to climate change and social justice by using creativity and building on learning by doing, learning by design, learning by feeling and action-based learning. By providing interactive and creative elements, young adults would be attracted to the topic and sensitized in a playful and positive way. Creativity and art are used to face a social challenge. As a result of the project, creative digital contents including video series (showing different decision-making situations), animated videos, podcasts, infographics in relation with fast fashion are prepared with the engagement of the youth and with the participants of the project partners. The project partners organize a four-round long, online creative competition for the youth about fast fashion. Solving the tasks of the competition needs creativity from the participating groups. The Fast Art – Slow Fashion project is implemented in a cooperation of 4 partners from 3 countries of the EU and led by the Hungarian EKO. The partners have experience in making digital materials, approaching a topic in a creative way, and they represent each pillars of sustainable development according to which fast fashion is approached: MASZK (HUN) represents the social pillar and is responsible for the creativity and artistic approach in the project; EKO (HUN) represents the social and economic pillar; while IDEC (GRE) and Aiforia (GER) are responsible for environment. These synergies contribute to exploiting our resources.
