This is the Royal Academy Summer Exhibition Preview, a 250-year old tradition that costs 575 GBP for plebeians and 850 GBP for VIPs, and advertises itself as, “With a glass of Champagne in one hand and a canapé in the other, you can be assured of being well looked after in the glamorous company of fellow art lovers in our exceptional galleries.” So you can imagine the range of choices its celebrity guests made.
