Amazon is the ultimate one-stop-shop for absolutely everything, but it's rarely regarded as a source of cool, new fashion. Keely Murphy, a 25-year-old LA-based stylist, has embarked on a mission to change that through her Instagram @fashionsecrets93, which spotlights Amazon's hidden gems. Every week on PAPER, Murphy will curate a list of Amazon fashion secrets, all of which you can buy here. This week, she's chosen 15 Halloween costumes to try, from Criss Angel to Britney Spears.
