Mariah Carey is the ultimate sexy diva, while Miley Cyrus is the quintessential good girl. What do these two singing superstars have in common? Apparently, their taste in fashion! We saw Mariah step out in her clinging purple sweaterdress, cropped black jacket and black suede boots last month, only to spot the Hannah Montana star in a practically identical outfit in Toronto over the weekend. We love that Miley put her own sweet spin on the outfit, but we can’t help but giggle over how similar they are! Tell us: Who wears her purple dress better? Mariah or Miley?
