Decide what you're dressing for. School? Work? Party? Show? Get-together? For example purposes, I'm going to say school.
Decide what limitations you have for where you're going. Do you need to be more conservative? Can you be flashy? Is wearing a hat appropriate? Etc...
For shoes: decide... Closed or open toes? Should you wear flats, or heels? Match or complement the color, but you might have to try a couple pairs before it turns out "right".
Sometimes it's discouraging to not have the pieces necessary to make the outfit you want. Just start swapping things out of what you already have, and magic could possibly happen. ;) Good luck!
