Today we’re giving some love to Mary Kate Steinmiller and her killer friendship bracelets. While she spends her days as the Senior Fashion Market Editor of Teen Vogue, her secret talent is creating some highly covetable and totally chic jewelry. In the age of the arm party, Mary Kate knows how to make a girls heart go aflutter—crystals, neon, pastels, and Liberty prints combine to make the perfect addition to your already crowded wrist. Head over to Fred Segal as soon as you can to snatch one up for yourself. Then again, one may not be enough…I know I want a whole armful.
