US pop superstar Mariah Carey dressed lightly to meet her fans in a Hong Kong record store yesterday. Corwin Wong Yiu-hang, 16, one of the fans who queued up to see her at HMV Causeway Bay said: 'One word - sexy. That's what she is. 'But I am a little worried she's a bit underdressed for the kind of weather we're having at the moment. She might catch a cold in that outfit.' Corwin recalled: 'I waited for her at the airport for two hours on Friday when she arrived and I got her autograph that day too. I've been a big fan for four years. She's so elegant and her voice is lovely.' Derick Hui Ka-kin, Wong's schoolmate, said: 'Mariah's just marvellous. She's the best female singer in the world.' Pooga Khatri, 12, who joined the autograph queue, said: 'She is not only pretty, but she has that inner beauty as well.'
