!HELP!!!!!!!!!!!!!!!!!!!!!!!!!…

Can someone please help me with my halloween costume? I have a halloween party in 2 days and I'm still trying to put together my costume. All I need is an orange and white striped tshirt. I'm going to be Phineas from Phineas and Ferb, and I can't seem to find a shirt like the one he wears on the show. Can someone please help me find one?
