No visit to Cambodia is complete without at least a quick glimpse of women performing the ancient art of Apsara dance, as depicted on the walls of Angkor’s temples. Wearing glittering silk tunics, sequinned tops (into which they are sewn before each performance to achieve the requisite tight fit), and elaborate golden headdresses, they execute their movements with great deftness and deliberation, knees bent in plié, heels touching the floor first at each step, coy smiles on their faces.
