Are the eighties over as a source of fashion inspiration? Tommy Ton's recent street-style photos seem to indicate a move toward easier seventies styles, and we found further evidence of the trend in the tie-dyed looks that brightened the Spring runways. "There's something about tie-dye that speaks to everyone," says Tory Burch, adding, "it's a little nostalgic but also feels modern." If Blumarine's caftan belongs cheerfully in the former camp, Proenza Schouler's Lazaro Hernandez and Jack McCollough gave the dyeing technique new life by applying it to sleek and of-the-moment active-sports styles. Kate and Laura Mulleavy of Rodarte, meanwhile, pieced together ragged, postapocalyptic looks using fabric usually associated with long-haired flower children. Are you ready for the re-dawning of the Age of Aquarius?
