The thing I want to know is why they don't have bigger sizes than 4T-5T.
I was about this age when I went to my first KU ball game and first saw the Jayhawk mascot, just before he claimed me as his own. But they never had Halloween costumes like that when I was a kid!
I should buy one of each size, just for someday.
(Even though the very thought of having kids is personally the most terrifying thing imaginable).
