Hollywood stars braved the rain to open Paris Fashion Week at L'Oreal's giant outdoor show Monday as rumours swirl of musical chairs at the top of fabled French brands. The cosmetics giant persuaded Jane Fonda - in snazzy silver sneakers - Kendall Jenner, Eva Longoria and several of its other brand ambassadors to walk in a spectacular public show in front of the gilded glory of the Opera Garnier. With invites to the big luxury shows strictly limited to the glitterati and fashion insiders, L'Oreal said it wanted to democratise the glamour of fashion week.
