I chose The ORIGINAL Chipmunks because that is what I grew up with. Me and my little sister loved watching The Chipmunk Adventure and singing along with The Chipettes. For his costume all I had to do was buy the hat and onesie. I had iron on paper and just printed out the "W" in place of Alvin's "A". I personally love Dave's "Willlliam!!!!" shout! ;)
You are such a creative woman! You crack me up with his photo shoots!
