“The sports shirt of choice is the Lacoste. Only the all-cotton model will do, the one with the cap sleeves with the ribbed edging, narrow collar, and two button placket (never buttoned).”
- The Official Preppy Handbook, 1980
I prefer two button over three button plackets, and in contrast to the advice of the authors of The Official Preppy Handbook, the bottom button fastened for men. I always wear mine with both unbuttoned.
