The Swedish superdiscounter Hennes & Mauritz took New York by storm in early 2000 with its high-style fashions at budget-minded prices. The colorful, loud, bustling stores are mammoth, but the departments are better organized than those at most full-retail department stores. The men's and women's clothing is ultrachic, and the prices are low, low, low. A real fave with teens, in particular. The main Herald Square store carries all lines, including babies, children's, and maternity wear.
