Sizing is good as far as the foot sizing goes, but they are a wee-bit narrow where the ankle joins to the calf. Takes a bit of working to get on, velcro isn't too bad, and they're really comfy once they're on.

I'm about '5''4, got the Medium sized uniform. There's two string ties and velcro at the bottom of each legging, so you don't really have to worry about it being too long. Top part was fine, ''bracers'' were made of cloth with elastic for the wrist and forearm. The Medium for me wasn't tight, but it wasn't ridiculously big either. You could say it wasn't tight, but had room for flexibility.

My only real issue was the hood. It looked fine, it felt fine, it's just that if you're wearing the (I believe it's nylon) mask under the hood, and you turn your head, it makes this rubbing sound. It doesn't make enough noise that others would notice, but it's -right next to your ear- which can be a problem.

As for an outfit to practice in, Halloween outfit, or wear out for paintballing/airsofting, it's great. But as for actually doing ninja stuff in, that'll be up to your judgment.
