Older sister Gigi, 20, layered a grey, cropped T-shirt underneath a long, duster-style coat. 

The light-haired beauty added a pair of distressed boyfriend jeans, cuffed at the bottom.

She finished off her look with a pair of strappy, yellow Stuart Weitzman eels, that appeared to be in honour of the event, as several celebrity pals were seen wearing similar ones.

Bella wore a sheer, print short-suit, complete with '90s-inspired platform ankle boots.

The 19-year-old stunner had her hair tightly pulled back in a small top knot.
