Well, for one, before we start judging, let me just say, I made this costume in roughly twenty-two hours, including food breaks, DDR breaks, and moments where I was just being lazy.
See, I decided on going to PMX a little last minute, so I was planning to recycle my Dirge of Cerberus Yuffie costume. But, the third night before the con, I got a message from a friend telling me there was a Kingdom Hearts gathering on Saturday, so I decided I would try to make a Kingdom Hearts Yuffie costume in the small amount of time I had.
But me, being the awesome procrastinator that I am, waited until 7 AM on Friday to start construction on it.
Fueled by Kool-Aid and baked potatoes, I finished sometime around 5 AM. On Saturday.
There were a few... pieces I'm not proud of. The buckles were made of cardboard, painted silver. The armbands, made of duct tape and spare posterboard.
The orange gloves kept ripping every time I took them on or off.
And the shoooes. They were brown wedges, covered in gold fabric, with brown fabric wrapped around my foot, held in place by duct tape. And a little strap hot glued around my ankle.

Either way, I think it turned out okay. And the best part: I'm pretty sure I was the only Yuffie there.
Oh, and I've lost weight/gained muscle since AX, so I think I look better.
So, leave some feedback. Pweeease?
