I'm Mareike and I'm crazy about YAYYAY Concept!


YAYYAY Concept is an online store of amazingly beautiful and affordable fashion for girls around the world. The T-Shirts are 100% organic and uniquely designed to reintroduce simplicity back into fashion.


I started YAYYAY Concept as a passion project in 2017 to explore the power of social media marketing.
