The song may be 'old', but I feel the look is still relevant.
Statement print leggings contrasted with a plain 'bralet'. Fun shades and quirky cap (optional i guess). Accessory wise-the brighter, the bolder, the more, the better!
Keeping the face bronzed and fairly neutral. Add a purple/mauve lipstick covered with a slick gloss to copy her lipstick style.
*disclaimer, this look is only for the fearless!* lol
