I bought this ninja warrior costume for myself for Halloween. As others have mentioned, it came in a garment bag and was made of good quality material. There are several pieces: pants with elastic waistband, shirt with zipper on the back, hood/tunic, mask/headband, and belt.
The length of the pant legs can be adjusted by folding the ankle portion to the desired length. There are 3 snap buckles that secure it, and gold ribbon that you wrap/tie around the ankles for the look. The wrist cuffs on the sleeves are similarly adjustable by folding back, but this time there are no snaps.
It would have been nice to have some pockets for holding keys, cash, etc, but I made do by storing a few things inside the front tunic piece held in place by the belt. The costume didn't come with any weapons or accessories, but I added a plastic sword, some plastic stars, and a pair of plastic sais. The sais were tucked in my belt behind my back. The stars were tucked in my belt in front. I strapped the sword to my back. This left my hands free to carry another ninja item or give out candy to trick-or-treaters.
