Is it okay for a college student to carry around a cookie monster purse?

I was at Walmart today for dog food and I went through the purse section, intending to buy a nice one. I saw some really cute cookie monster, grimace [the trash can monster], elmo, tinkerbell, betty boop, etc purses. Since I cant stand tinkerbell and I looooove cookie monster [even at age 19] I so wanted one. I didnt buy it today, though. Would it be weird for a 19 year old to have such a purse? Im planning on taking it to university with me, and when I go to university/college, i'll be 20, and I'll keep the purse until after I graduate, probably. Am I insane for this? Its such a cute purse! br

Ps im asking this in college and fashion section for better answers.
