When I think of fall the first thing that comes to mind is thunderstorms since I love listening to rain hit my window :) Here's what I came up with, sorry in advance for my drawing skills...

Outfit Item: Thunder Storm Toga
Held Item: Lightning Bolt
Head Item: Thunder Storm Headband
Wing Item: Lightning Bolt Wings
Back Item: Rain storm





In case it's hard to tell, the blue part of the togas are supposed to look like rain. It was kinda hard to achieve that affect using my tablet, but I tried :)
