Homecoming Outfit...HELP!

So with homecoming only a few months away, I am already thinking of what I want to wear the day my sailor is back in my arms. It's going to be winter and most likely freezing, but of course I still wanna look smokin' hot for my man! ;)

I already have an outfit in my head that I want to wear but I can't seem to find it anywhere I look! I've been scouring online sites to see if I can find anything, but so far there is nothing that really catches my eye.

I also have a hard time online shopping because of my size. I am tee tiny and most the time wear a zero in pants and an xs or small in shirts. It's extremely annoying! I wish I had a more womanly body...

Anyway, the vision I'm seeing in my head is a sweater dress with some leggings and a gorgeous pair of boots! I think that would do the trick...I'm gonna have to wear a jacket but I at least want to look good underneath. I need ideas! So far I've found ZIP, ZILCH, NADA that I like.

HELP!!! I would greatly appreciate any good links or photos of something that fits this description...I still have time but it will be here before we know it.
