No affiliation. I don't have an iphone or ipod and can not mess with it but I wonder if this App has a gear application. Even uses "real-time weather data".
"Cloth is an app for iPhone and iPod touch that makes it easy to save, categorize, and share your favorite outfits. The app also lets you send your favorite outfits to this site, for us to post for the world to see.
Cloth uses real-time weather data from our friends at wunderground.com, to pull the perfect outfits from your closet for your current weather conditions."
