The #FreeTheNipple movement still an Instagram issue – and nail artist Mei Kawajiri is fighting back with nipple nail art.  Karajiri created the nail art with different skin colours and nipple piercing effects.  Her Instagram, @nailsbymei, is full of amazingly intricate nail art designs we can’t help but want, and Kawajiri’s nail art has since been featured in an advertising campaign by Balenciaga.
