RUNWAY TO REALITY : Tanked Up

The little knit tank dress is a warm-weather staple. For spring, New York designer Oscar de la Renta showed one in luxurious sky-blue cashmere, with a matching cardigan knotted casually around the shoulders. The dress and cardigan, which carry the Oscar de la Renta by Ballantyne label, cost a total of $1,025. I. Magnin carries the outfit.

For shoppers with cashmere taste on a cotton-knit budget, Liz Claiborne offers the exact same dress style. One in snow white is $68; the matching cardigan with embroidered sleeves is $110. This practical little ensemble for hot weather is available at the May Co. citywide. Total price, $178.
