The best new collection ever of summerweight sport jackets and slacks is available this year. As shown here on these pages, in the delightful climate of San Francisco, across the Golden Gate in suburban Sausalito and Belvedere, they go from boat dock to golf course, from Friday cocktails to Sunday cookout without weight or wrinkle. The big news is in the lightness of the jackets, which are not wash-and-wear like the slacks that go with them but are of fabrics such as challis, silk, Viyella, cotton and the new Shetland shown in color on the opposite page. It weighs only eight ounces per yard. The wash-and-wear flannel slacks ($17.50, Brooks Brothers) are of 80% Orion, 20% cotton, a blend as carefree as summer.
