This is such a great astronaut suit! Our 4 year old is obsessed with rockets and space and wanted to be an astronaut for Halloween. He has been wearing it since it arrived! It is authentic looking and he likes the real belt, patches and straps. It is a thin white material that you can see color through. One will probably need to wear clothing under this costume. I really like this costume and would reccomend it. We also bought a helmet which completes the look.
