This costume is made of good quality material.  A lot of costumes out there are flimsy and tare easily.  This one is very durable.  I bought this for my daughter for a school presentation....she was representing Neil Armstrong.  She also wants to wear it for Halloween and asks to wear it often.  She is 8 and this costume fit her perfect.  Definitely not just for boys.  It is great for any child who aspires to be an astronaut or at least dress like one.  The only real down side is the hat is really big.  I had to adjust it for her so tightly that it almost went past the Velcro.  Very realistic costume as well.  I highly recommend it.

Update 12/16/16:  We still have this costume and have had 3 of our 4 kids wear it.  Still holding strong and still in great shape!
