Kate ensured all eyes were on her as she arrived at Carine Roitfeld's (Rear of the Year competition-themed?) cocktail party at the Hotel Shangri-La in a completely see-through embellished jumpsuit and black blazer that actually left her bum on full view for all to see. That's what we call cheeky.
She appeared to don a bodysuit under the catsuit, and finished off with a pair of black ankle boots layered on the inside with animal print.
What do you think? Is this age (or, indeed, ever) appropriate? Or does she manage to pull it off?
