When Sarah Hoover was a young girl in Indiana, her grandfather would regularly take her to museums, where she admired pointillist paintings by Georges Seurat and Camille Pissarro. Twenty-odd years later, she’s graduated to the more contemporary art of Ellen Gallagher and photographers Inez van Lamsweerde and Vinoodh Matadin, whom she works with at New York’s Gagosian Gallery. And just as Hoover’s artistic tastes have changed over the years, her wardrobe has evolved to meet professional demands. “When you’re trying to sell art to a 50-year-old millionaire, you can’t dress like a kid,” says the 28-year-old. Nor can you rely on a uniform of corporate penguin suits. And so, Hoover favors T-shirts from the Row and J. Crew pullovers paired with sleek pencil skirts from Roland Mouret and Azzedine Alaïa. (The Preen mixed-python number she’s wearing here would fit right in with her collection.) For her recent wedding to the artist Tom Sachs, though, Hoover came full circle, having the ceremony at the Indianapolis Museum of Art. She went traditional with a white lace Carolina Herrera gown and gold bow-bedecked Christian Louboutin pumps. Still, her shoes did get some tweaking from the groom: “Tom gold-leafed the bottoms so they weren’t red,” Hoover says.
