It's time to start brainstorming for your very own Fabby Halloween! This year, we're kicking it off with Katy Perry's sequin-injected California Gurls look. To get the candy-girl's whimsical look, start with a pink bustier top and high waist denim shorts ($20, originally $44), then add your own Fab embellishments with glittery sequins and candy — rainbow lollipops are key. Finish the look with a pair of stripe knee-high socks ($24 for three, originally $30) and sneakers, or a pair of red or white heels to up your flirty factor. The more candy-color and glitter, the better! Get inspired and click the items above to shop the look.
