Gala Darling has a couple of great posts about the benefits of daily outfit photos, here and here.
I do mine for several reasons; here are some of them:
1. They provide me with a record of what I wore, so I can a) go back and laugh at silly outfits from the past, b) remember outfits that worked particularly well so I can repeat them again, and c) chart the evolution of my style over time.
2. It’s fun to share my outfits/style with the internet and receive comments on the photos.
3. When you have a compelling reason to get dressed nicely, you’re likely to dress nicely more often. (I used to be a jeans/sweatpants/hoodies/T-shirts girl before I started wardrobe_remixing in 2006!)
4. Full-length self-portraits give you a better perspective on what looks good and is flattering on your body than a mirror does. Taking outfit photos helps you to learn what works for you and what doesn’t.
