The New York Times has put together a wonderful compendium called the Red Carpet Project. It covers red carpet gowns from the past 15 years, and you can sort them by color, designer, actress, silhouette, even sleeve length. There are best dressed and worst dressed (at least according to the Times editors who participated), big names and little names, bombshell and demure, haute and outrageous.
Glamour Girl has written about a lot of these gowns, most recently here.
It’s so much fun to look through them, put aside a little time. Here’s a brief summary of the project by Eric Wilson, and here’s the whole shebang.
