Polka dots are having a moment right now, with Yayoi Kusama's upcoming retrospective at the Whitney Museum and her collaboration with Louis Vuitton. The normally twee-looking print gets a makeover when combined with unexpected materials, like chambray. And this slouchy menswear-inspired shirt looks equally as good paired with trousers or a skirt.
