Blue on blue is just a classic fall-back when I'm in need of some color, but can't come up with anything creative. (Swap out the blue sweater for a gray one and you've essentially got an old outfit of mine.) It really is a lot brighter this way, though. When the sun finally comes out after a long winter, it's hard not to want to put on something a little more cheery!
PS. I've been catching up on a lot of tumbling over break, so be sure to stop by my tumblr if you haven't been in awhile.
