So I was thinking it would be very fun and easy to have PJ ninja night(s) at Kumoricon. If you are tired of wearing a cosplay all day and wanna lounge in some PJ's during the night times (or if you are attending night time panels), then this is an easy idea, plus it brings out your nerdy fashion.
All you'll need is some PJ's and a T-shirt for the mask. Here is a video link to make a mask from a shirt:

I would like to see if we could form a group out of this.
