My only grievance about this year's shirt was that Confuzzled 2013 wasn't printed on it. The con staff did say they didn't do it deliberately so that people who were conscious about wearing a furry shirt in public. I think that next year the con staff should have the shirt come with an iron-on transfer, so people can iron on the logo for the con if they want to.
Also, maybe they should stock up on more XL and larger sizes. I wanted an XL but settled for a L; the XL was more so I could wear it outside my fursuit.
