1977 by Sandra Garratt, a designer who had worked with Halston and Mary McFadden. Familiar with haute couture with a haute price tag, Garratt set out to create clothes that worked for her. What she came up with were 24 multi-use, one-size fits-all pieces that lets the woman, not Ralph or Liz or other designers, define "the look." Garratt's line, Multiples, is available at Coats Unlimited and Hudson's for adults and at Peanuts and Gould's for children. A competing line, Units, has its own store in the Twelve Oaks Mall and Fairlane Mall. "You can make Multiples anything you want," says spokeswoman Jill Bace, adding that the basic pieces can be put together in such a way that they can go directly from the office to evening wear. "It can be funky, and it can be conservative." What it can be is everything from slacks and top with a bolero jacket for weekend wear to a bubble dress in shocking pink for evening. The knit fabric has been selected to flatter most bodies. "Once people adapt to (modular dressing), understand it and take it into their lives, they can't imagine being without it," says Bace. But knowing just where to begin when peering into the cubes full of tubes and peg pants and jumpsuits and cowls is sometimes difficult. Stepping out of a dressing room at the Units store, one prospective shopper complained that the dress "looks like a sack." However, after the knowledgeable saleswoman tied a cowl at the waist and topped it with a jacket, the customer was pleased with the results and the possibilities. To help shoppers get the most out of the modular dressing concept, both Units and Multiples salespeople are trained to show them how to put the various components together. Units, for example, sends store man- agers to their Dallas, Texas, head- quarters once a year to be updated This Units outfit combines three basic pieces: a tank top, a straight skirt and and a classic jacket. The outfit, which costs around $70, is worn with an oversized belt. SPRING '89 75
