Not my boys.
Nico and Lucas spent all morning playing pirates. They don't have pirate costumes, but did that stop them? Of course not. You don't need expensive costumes when you have paper, tape and imagination.
Nico drew, colored and cut out a pirate hat, eye patch, shirt, parrot, peg leg, and hand hook. Then, using scotch tape, he taped them all over himself. Then he ran around the house shouting, "Have ye seen the white whale?". It was way cute.
Then they went off to their room so they could build a pirate ship out of tinker toys. What a fun filled morning.
