Today's Everyday Fashion: Periwinkle Please

I was running super-late yesterday and I threw this outfit together for lunch with a friend. Generally, I come up with outfits one of three ways:

1. I am craving a particular color or print (like leopard) that day, and just have to go for it.
2. I have a practical aspect of my day that determines a starting point - such as what shoes to wear - and then I plan the rest of the outfit around that piece.
3. I look through inspiration photos to come up with something out of left field.

Today's look was a result of #1. I was craving periwinkle from the moment I woke up, and just couldn't leave the house without putting it in my outfit somehow. Thankfully, I still have this sweater from more than two years ago, so I pulled it out of the back of my closet. I then promptly went to town adding some other favorite colors like a chartreuse shirt (also pretty old) and a green statement necklace. What's your process for selecting what to wear in the morning?
