Costume designer Aaron Patrick Turner makes the metaphorical silk purse out of sows' ears for many a local theatrical production. Working on lavish budgets or on the "Can you get it free?" plan, Turner has earned a reputation as a meticulous creator of beautiful period costumes. Among his best are the clothes he made for Trinity Shakespeare Festival's Twelfth Night, Amphibian Stage's Icarus, Contemporary Theatre of Dallas' Oldest Living Graduate, Rabbit Hole and The Cemetery Club, and this summer's elegant 1930s wardrobe for the comedy The 39 Steps at Stage West. As local stage costumers go, Turner's got the title of "best" all sewn up.
