Before you slip on a pair of weekday jeans, consider your workplace and what is appropriateif you are a banker or a lawyer, you might be limited to twill trousers even on Casual Friday! But if you work in a more casual profession, try upgrading a sleek pair of jeans with a structured blazer. For a classic look, pair a black jacket (like
Sarah Jessica Parker's velvet number) with dark denim or a bright white tuxedo design (like
Gwyneth Paltrow's) with a lighter or acid-washed pair. Think suit and match light colors with light and dark with dark.
