Of all the Instgram pics I saw from last night's Serpentine Gallery party in London, it's this one of fashion editor Lucy Williams that stood out from the rest. Her asymmetrical Tibi dress shows just the right amount of skin and the ruffles add good evening drama (though I could easily see this dress during the day with flat, lace-up gladiators). Red Aquazzura sandals amp up things perfectly. What's more, it's the kind of winning outfit that can be worn again and again. Well done!
