Tina's Tips
Add Some Color
"It's the fastest way to brighten up an outfit and lift your spirits," says Knowles. "It can be in your necklace, your nail polish, your lipstick."

Don't Over-Coordinate
"There's a misconception that you have to match your shoes and your bag. It can be so cool to add a patterned or off-color heel."

Befriend a Salesperson...
"If you're easily overwhelmed when you shop, remember that store employees know what's in stock, and they love to give fashion advice. Working with one is like having your own stylist."

...And a Tailor
"Take the time to get your clothes to fit. It makes a difference."

Necklace, Lulu Frost. Shoes, Jean-Michel Cazabat, Barneys New York.
