Most women spend a lot of time putting together their basic urban outfits—suits, party dresses and weekend staples—but leave shopping for that last-minute beach getaway until, well, the last minute.

Enter Tomas Maier, the German designer who has made a career out of treating swimwear just as seriously as any other component of a woman's wardrobe. Maier's sexy swimsuits range from itsy-bitsy, fire-engine-red bikinis to black, figure-flattering one-piece suits, and are decorated with everything from a rogue flower to lavish fringe. To cover the ground between beach and hotel, Maier provides silk jersey cover-ups and caftans, sensible track suits, shorts and tees.

"My clothes are designed exclusively for moments of leisure," says Maier. "There are bathing suits, comfortable things for the plane, and even a little something to open the door when you order room service."
