The exhibition, which will run until June 21, will feature photos of some of the world's best-known models and celebrities taken during Gilles' 30-year career with Elle, according to Elle Hong Kong marketing director Jennifer Cheung.
The exhibit will include images of supermodels Noami Campbell, Linda Evangelista and Cindy Crawford as well as film icons such as Audrey Hepburn and Sharon Stone.
Cheung said the promotion would also include a lucky draw and a fashion presentation, reviewing women's dress trends from the last century, to build awareness of the month-long exhibition.
