Since fast fashion's birth, clothes got cheaper, people bought more than they needed, and in doing so many companies went on to create low-quality garments made by workers who were and often are still treated and paid extremely unfairly. Not to mention mass productions truly awful damage to the environment.
Fashion is facing a big challenge, making people understand the real costs. This, sadly, is not just in the manufacturing industry but also related to the arts who face similar issues.
Fashion courses often focus upon the more artistic side, bespoke and original design, what they lack is the whole process of making them. Where quality is an afterthought and not enough time goes on the expertise that you gain with a solid foundation of making clothes. You simply need to also understand the repercussions of each step before you start to make them.
In fashion and other arts, sales are sometimes strongly related to the brand/artist's reach or marketing strategy more than the item itself, we need to be aware that if we open a fashion brand it is not purely for the money but for the passion you have for it.
