The Saint Louis Art Museum (www.slam.org) has gone mad for fashion — perhaps you've noticed. With an ongoing exhibition about the Paris millinery trade's influence on Degas and Mucha's art, and another that explores the work of modern haute couture hat designer Stephen Jones, the museum has clothing on the brain. That thread is further worked in this year's Art Hill Film Series, with four films that feature Academy Award-nominated and -winning fashion. Tonight at 8:30 p.m., you can see Alfred Hitchcock's To Catch a Thief. This 1955 classic stars Cary Grant as John Robie, a retired jewel thief who now lives peacefully on the French Riviera. Grace Kelly plays opposite Grant as Frances Stevens, a young beauty with a fabulous jewel collection. When a rash of high-profile thefts are pinned on Robie, he and Frances team up to trap the culprit in the act. Food trucks and concession stands will be set up at the top of the hill and ready for business from 6 to 8:30 p.m., and local bands will play while you eat. Admission is free.
