During an episode of MBC Music Core last month, the girls of Sistar performed their latest summer single “I Swear” and won the No. 1 spot on the show. They wore coordinating stage styles pairing pink and white from Forever 21, an American clothing brand which you would not be unfamiliar with. Hyorin was in a white Life & Love Muscle Tee ($15), paired with denim shorts & checkered shirt tied around her waist. Bora could be seen wearing a simple Tartan Plaid Shirt ($20). The checkered shirt is tied above her waist. Soyu wore a pink Love LA Muscle Tank (
$13 $9) which is paired with a short tube top inside which really gives her a sexier appearance.
