Fashion-forward styles take a while to filter down, and decidedly new looks, such as miniskirts, take even longer to catch on (if they ever do). But this season's trends are well within the norms of mainstream dressing, so much of it will be immediately available. Here's what local store owners are featuring: Another strong trend at Hudson's is the Oscar Wilde, a dandyish look with vests, coats and poet shirts. The boot-length slim skirt, in vogue a few years ago, is making a comeback. This will be a big blouse season, with such features as lace trims, shawl col- lars, jabot necklines and embroidered crests. Fringe is a major accent — fringe on sweaters, on leather and suede items. Vests are fashionable especially in luxury fabrics like brocade. Also shown are vested dresses (a dress that looks like a vest). Animal prints — leopard, tiger, zebra, dalmation, — are everywhere, even in earrings. Lovely new fabrics being used for fall include mohair, cashmere (especially in sweaters and skirts) and colorful plaids. Wool jackets are trimmed in leather. Warm colors, like burgundy, plum and olive are in. Diane Mondry of Diane V in Birm- ingham purchased many cashmere sweaters in all the basic colors. "Sweaters are strong, 'she notes. In ad- dition to a complete cashmere line, Diane M will show fisherman knit and glen plaid sweaters. Some of the new designers at Diane M are Cynthia Steffe and Jamie Herzl- inger. Steffe is a former associate of Donna Karan and features draped, com- fortable clothing. Herzlinger's designs in wool jersey are great career choices. Mondry also notices the strong folkloric and ethnic themes off all fashion dressing. Arlene Green of the FALL '89 49
