Fashionistas with no time for real window-shopping can fire up their browser windows and sift through the racks at Net-a-Porter instead. Even if you can't afford most of the togs you see — the site sells everything from dresses and handbags to shoes, jewelry and sunglasses — it's still fun to browse designer goods, like the $335 crocheted blouse by Phillip Lim and the $4,300 python cut-out boots by Miu Miu. The site's clean, no-nonsense design lets you find what you want fast. If Net-a-Porter leaves you empty-handed, check out Vivre or Yoox.
