If you're ever in the mood for some serious luxury, and we're talking exclusive, beautifully made luxury, 20ltd.com is your go-to site. The British concept store only sells 20 limited-edition products at a time, made exclusively for the site, including a Derek Lam asymmetrical anorak and a Longchamp crocodile bag. Prices reflect quality, and range from $200 to $100,000. Maybe not affordable, but fun for window-shopping, nonetheless.
