I've been messing around a bit with one of my favorite apps, Stylish Girl (which I very highly recommend! It's completely freeeeeee!!)
One of my favorite features is the "Outfits" tab. You can use items from your closet and/or wish list to create and save outfits--it's really nifty.
Here is a little outfit I put together with some items I am currently loving. I'm really, really getting tired of winter (I know--already?!) and can't wait for spring to hurry up and get here! Hence all of the spring-y colors. If you wanted to be more realistic, you could skip the necklace and add a scarf and coat instead, I suppose :)
