SISTAR really is the girl group of the summer, and it's not only because of their music. The women have adopted a signature look for this summer's sultry performances. With their sequined shorts, muscle tee crop tops, and chunky gold jewelry, it's the ideal rock star look for the chick who still wants a little sparkle with their grunge.

Element Moon Flower Cropped Muscle Tee, from Swell

SISTAR's not the first to jump aboard the cropped muscle tee train, but they sure are doing it well. We're in the golden age of graphic muscle tees, so buy them up while you can. They're the new basic white t-shirt - they look great alone, under a cardigan, over a maxi dress, or draped over a pencil skirt. This one from Swell is versatile and chill.

Bling Jewelry Gold Plated Chunky Beaded Round Link, from Bluefly

This necklace is proof that chunky gold jewelry doesn't have to come off as gaudy or cheap. This is a feminine necklace that makes a statement. But don't be afraid to make too much of a statement - there's no such thing. The gold on here blends in seamlessly with the panache and flair that this outfit exudes. Own it!

Distressed Sequin Denim Shorts, from Forever 21

Take the boring cutoff jean shorts one step further this summer. The jean short essence is still the same. You can still pair these with anything from a white t-shirt to a glittery rainbow crop top, it's just a little bit more fun when you do.

Platform Block Heel Sandals Black Snake, from Missguided

SISTAR has switched up their shoe game a little throughout the summer (sometimes adding the K-pop trend of meshy knee socks). But the platform block sandal is a killer look to show off some leg with sequined shorts, and the chunkier heel makes it one you can wear all night without sore feet.
