I went to a panel talk called "Is Fast Fashion Slowing Down?" yesterday. Founders of fashion start-up companies agreed that both fashion designers and consumers are starting to feel guilty about human, social and environmental problems of fast fashion, and this is the time we start a conversation about sustainability and transparency.
The fashion industry can't be 100% sustainable overnight, but we should take a step and there can be different approaches.
Good styling tips, good tailoring service can help people buy less stuff. We can find more young designers who are conscious and ethical.
Personalization, data analysis can help people find the best products for themselves. There are also tech innovations such as "Fabrics from orange peel, leather from mushrooms" (This amazed me)
Use KOL influences (Kate Middleton is wearing same clothes more than 2+ times but it's cool!), Raise social awareness such as #whomademyclothes, Award sustainable brands as Positive Luxury
Government subsidizing, Tax and fine can be also useful
