Hayley Williams in a photoshoot for Paramore's January 2012 Alternative Press cover

These Cheap Monday Moss Ice Narrow Skinny Denim Jeans from Hot Topic ($65.00) are really similar to the mustard-colored skinny jeans that Hayley Williams wore in Paramore’s January 2012 Alternative Press photoshoot. I believe that her exact pair is from Cheap Monday as well, but they are a higher-waisted style like these.

Hayley also wears the Sailor Girl Intarsia Cardigan from Betsey Johnson (sold out) and red Converse Chuck Taylor All Star Hi-Tops ($45.00).

DEV in her music video for "Naked"

DEV wears the “Precious Metals” Gold Color Lightning Bolt Hoop Earrings from Han Cholo ($238.00) in her new music video for “Naked” featuring Enrique Iglesias.

She also tries out a new hairstyle with blunt bangs and pin-straight shoulder length hair. I’m not sure if it was a wig or a weave, but she’s already back to her usual shorter hairdo.
