Year 2021 marks 20th anniversary for Twins. After recording a Chinese variety show together earlier, Gillian Chung (鍾欣潼) and Charlene Choi (蔡卓妍) went to a supermarket and were discovered by the netizen. They took photo together but Gillian was dressed in a black outfit with a cap and slippers which reduced her celebrity charm. As for Charlene, she wore a black top with denim and increased her feminine charm. Many netizens remarked they failed to recognise Gillian and resembled Charlene’s assistant.
Although Gillian has beautiful look, but she tends to gain weight easily that causes her to have good and bad fashion senses at times. Sometimes, she will wear loose clothes to conceal her flaw with chunky shoes but it makes her look swollen instead.
