Being a teacher (and an industry professional working with recent graduates) I see that most of students feel so overwhelmed with what they need to know to thrive in this highly competitive industry, adding sustainability on top of it seems to be too much.
They may understand the issues, but often feel that it doesn’t matter when they finally start working, meaning that what matters is being quick and being the best.
Many students finish their BA with a lack of knowledge on textiles and fibres, which also means it will be difficult for them to source and choose alternative materials based on the desired performance of the garments they are creating.
Their lack of interest in manufacturing also means they clear their hands from decisions on garment construction, which means this ends up decided by the manufacturers (who will make it the cheapest way), not taking into account the on-going use of the future garment, the ease of repair and its disassembly.
This means that schools have the responsibility of having sustainability has the backbone of fashion design education, not just an add-on subject and not just on Masters level. Teachers need to have it has the backbone of their discourse. And right from the first day of the BA.
