Winning this category for the second straight year is a pricey boutique that has allowed many a mom-to-be to leave the house feeling sexy even after gaining twenty pounds. So what if dresses go for about $150 and suits sell for $250? Just think of it as a two-for-one deal. They stock an especially good collection of eveningwear. "I really do love the clothes here," one bulging acquaintance says. Then she gives this shop the ultimate endorsement. "Actually I'd wear them even if I weren't pregnant."
