Valentino Garavani achieved one of those rare feats reserved for a very few: He needed no last name. “Valentino” conjures many things—Italian artistry; the color red; exquisite gowns worn by Liz Hurley and Anne Hathaway; and, of course, Giancarlo Giammetti, his partner in work and in life, the man who oversaw the business side of the brand. Together, they built a couture house that dressed royalty, actresses, and socialites for more than five decades. In a strange twist of fate, the Portuguese artist Joana Vasconcelos opened “Venus” in the same week Valentino died, at age 93. Known for monumental, site-specific sculptures made from materials as varied as fabric, ceramics, and industrial objects, Vasconcelos here presents abstract works that echo the scale, ornament, and theatricality of Valentino’s world. It’s an artful farewell to the “last emperor of fashion.” —Elena Clavarino
