Let's take a look at your daily routine. You wake up, shower, brush your teeth, open your closet, then it hits you. "What am I going to wear today?!" I run into this problem everyday.
I solve this problem with dresser, your closet on your phone. You take a picture of your clothes that are autocropped and stored in a fancy little library and then use those pictures to put together outfits. The app also stores a history of when you wore each item so you never have to wonder if you wore that shirt already this week.
Other ideas are in the works too like a social network for sharing your favorite outfits with friends and a wish list so you can see if those pants would go with your shirt back home.
