Here's Kivi's 2010 Halloween costume. Not pictured are the matching trick or treat bag made from remnants, and the other flower ornament in her hair (it's on her other temple).
This year, aside from picking what she was going to be, I chose most of the individual details of her costume. She's currently very big on the color teal/turquoise, so when I saw the fabric, I knew it would be perfect. I told her about it, and she OK'd the choice from my description, so I acquired it the next time I was at JoAnne's with a 50% off coupon. She picked (and paid for) the parasol on her own, and chose which style of flip-flops she wanted (pretty slim pickings this time of year!).
She's wearing Teva flip flops (instead of the elaborate - and tall - wooden sandals that Geisha wear) and the tabi socks are converted from regular socks.
Here are the individual stories about the different parts of her costume:
