I chose Stitch because I love him as a character and I'll choose something blue over pink any day. I'm not much of a girly girl and pink (well actually pastel/light pink) is my least favorite color in the spectrum. I would say the same exact thing if the Stitch hat was currently buyable and the Minnie hat was the most rare item in MyVMK. I go based on what I like...not value. Plus...I have a real Stitch hat I got in Disneyland several years ago.
