For evening, the guide recommended a two-piece dress that could be worn informally or dressed up. The blouse should have a neckline "that can be worn prim or plunging" and the fabric should be a dressier synthetic, silk or jersey.

Rounding out the wardrobe was a "spectator sports ensemble" of a skirt, colorful strapless or halter top, and a bolero jacket in matching color.

Finally, a woman on the road would need a "rugged-life costume" of sports blouse and shorts (or the flattering pedal pushers). Because "slacks are frowned upon" in many resorts, especially in the East, women were advised to wear pants only when engaged in active sports.

Women were also advised to take along accessories: low-heeled shoes, one "roomy purse" and an evening clutch, two scarves, two sets of jewelry and two belts. A stole might be added for evening.

Men were advised to take a "gray suit and a blue suit, a tan sport coat and brown slacks for a total of nine outfits."

The guide cautioned against wearing "the wildest and brightest clothing they can find" because "garish clothing would stand out and reduce the versatility of the wardrobe."
