Adam Glassman's advice on shopping for separates.

Q: I usually buy one piece at a timeā€”and then discover that nothing goes together. Can you help?

A: Separates are terrific, but random purchases are challenging. Think systematically: To build your wardrobe, you have to know what's already in it. Before each season, try on your clothes and give away anything superfluous, then make a list of what you need. Or go to, a new site that lets you photograph your wardrobe and create (for free!) virtual outfits that you can mix and match. You can even hire an online stylist ($25 and up) to develop personalized looks, packing lists, or shopping strategies.

Mix and match styles using an online dressing room. E-Paper dolls anyone? Test out your wardrobe on a mannequin in the virtual dressing room at and see which combinations work (and which don't).
