Dress Code

Charla says that women in their 30s can wear a chunky knit and still look sexy. Charla created a more revealing look for her 30-something model with slim pants and a form-fitting shirt underneath her sweater, all from Neiman Marcus. "The younger you are, the more you can reveal," she says.

For an older woman, Charla chose something less revealing but just as stylish from Saks Fifth Avenue. "When you are in your 60s, you can wear a chunkier knit that's a little slimmer and more flattering," she says. "Putting it with kicky boots makes it pop and makes it edgy."
