1. Take Selfies of Your Outfits: Take a tip from your favorite bloggers, and photograph a look when you really love it. This doesn't mean you have to post it on social media, just keep it for inspiration.
2. Always Carry Band Aids in Your Wallet: Just in case your new flats or boots dig into your heels on your commute. There's nothing worse than limping around in pain for the rest of the day. If you want to be extra precautious, keep a spare pair of sneakers under your desk for a quick postwork change.
3. Pick Out Your Outfits the Night Before: 20-somethings lead busy lives and can feel constantly pressed for time. Shave off minutes of getting ready in the morning by prepping your outfit the night before. Even simply envisioning what you'll wear before you sleep can help. (Just don't forget to check the weather.)
