An aviator cap for your little jet setter

My littlest dude is obsessed with jets and flying right now. It's a preschool thing; they're learning about all forms of transportation. How much would he flip for an old-school aviator cap (US$35)?

I spotted this Etsy find on Cool Mom Picks. It's a velveteen cap with a soft flannel lining and wool felt aviator goggles...you'll have to find your own scarf. Would be a fun addition to any dress-up box. (Dare I say Halloween costume?)
