L.K.Bennett — aka Kate Middleton's go-to shoe label — held a tea luncheon in LA, and invited British beauties Poppy Delevingne and Rosamund Pike, as well as Revenge's Christa B. Allen. To dress the part of "ladies who lunch," the ladies brought their styling A-game in equally fresh Spring ensembles. Delevingne stepped out in a pastel green maxidress, which featured a thigh-high slit, then completed her look with a chunky gold necklace, a lilac L.K.Bennett clutch, and gold gladiator sandals. Pike chose a classic pairing — an LWD by L.K.Bennett and black pumps — while Allen mixed pastels and brights via her Oday Shakar floral chiffon mini. Now, it's time to decide: which outfit gets your best-dressed vote?
