Marketing tips for a fashion startup

Me and my partner have launched a new slow fashion brand – Nome Studio with a mission to communicate the value of underused natural fibers like yak wool and create garments that combine function, beauty, ethical sourcing and longevity. We would really appreciate if someone here has any tips(dos and donts) on marketing strategy. What should be our approach? We are doing all the basics but what can we do to stand out? Would really appreciate if some of you share your success stories.
