First up, Bella wore a pretty white lace babydoll minidress with puffy off-the-shoulder sleeves, a lace-up corset-effect bodice and a frilly hem. This sweet, youthful sundress is from Australian label Daisy, which is stocked at Opening Ceremony and is £224. Yes, before you ask, this store does ship internationally.

Then for her evening celebrations with her sister, Gigi, Bella changed into a daring, fitted black dress. From the front, it looks like an elegant satin pencil dress, however, each side has a two-inch slit held together with black laces, and the shoulder straps are made out of studded black leather. It's a Liz Hurley–esque LBD.
