On a good day, shopping can be glorious—the thrill of the hunt, the triumphant score (fabulous shoes! in your size! on sale!). On a bad day, there's nothing like a cruelly lit fitting room or a hit of sticker shock to make you feel fat, old, anxious and broke. The secret of guilt-free shopping is to spend what you can afford and buy what you need. 

Next question: What do you actually need? Find the gaps in your wardrobe and fill them with style.
