From 2011.

This is my best friend atop of Mt. Fuji wearing my (very slightly modified) Stitch Onesie.

We were both climbing Fuji; this was taken (by me) on the way down on a break to eat some carbs. You can see the rest points we stopped at on our sticks, here.

Personally, I just liked the angle.

We didn't wear costumes the whole way. I didn't wear any; didn't really think ahead. The friend grabbed mine and put it on about halfway on our way down. Many pics were taken, but this is one of the more interesting/artistic ones, I think.
