This costume is awesome! I purchased it for my daughter's upcoming Secret Agent Spy Party.  She just turned 7 and is average sized.  The coat fits her well with room to grow.  The hat fits her well too.  She can actually see behind her with the rearview glasses which is awesome.  And the red lens to read the spy messages is pretty cool too.  Overall, this was a great purchase and I'm so glad we bought it!
