Depending on your build, I would say a youth large might work! I am 5'9 and 118lbs and I can usually fit into a children's large although sometimes it feels a bit short on me. It doesn't feel awkwardly short, I am just used to wearing longer length tees usually. I wonder if calling the merchandise line would also bring you luck. I was able to snag a
Disneyland "spirit jersey" this summer by doing so. It can't hurt to try!
The Disneyland site lists that phone number as "Merchandise Guest Services. (877) 560-6477"
