While grabbing lunch with a friend in Beverly Hills on a hot day, Ali Larter sported a preppy ensemble — blue-and-white striped blouse with white cuffed shorts — that she turned cool via knockout accessories. On her neck she wore a colorful bib necklace, on her eyes round tortoise sunglasses, and on her feet tan ankle-strap sandals. Then she threw all her essentials in a tan suede tote bag. Ali's warm-weather getup proves that mixing preppy pieces with nonpreppy accessories is smart. Just pair your striped work blouse with shorts on the weekend, then throw on a statement necklace, chic sandals, and quirky shades to achieve Ali's daytime cool.
