Coco, 13, loves fashion, has her own eclectic, eccentric style, and dreams of becoming a famous style icon. But on the first day of school, when she is called Coco the Clown for the way she is dressed, she decides to leave her vintage dresses, leopard boots, and striped socks at home and go through life at school as a "grey mouse". Anonymously, she runs a fashion vlog as the "Style Tiger", which becomes a big hit. Will she become a famous style icon after all? And will she finally draw the attention of Bruno, that quirky boy at school? Slowly but surely, Coco learns that she must just be 100% herself.
