The Chipmunks Alvin and Simon Costume

Jalen is my 6 years old boy that came with the idea to be Alvin for Halloween he watches the cartoon(Alvin and the Chipmunks) He said he likes Alvin because he is funny like him friendly and cool. He wanted his bother that is 3yrs old to be Simon. I use one of his cousin sweaters that is 15 yrs old and went to Michaels art and craft store to buy the yellow felt to make the letter A and sow it to his sweater. He use his dad's hat. He was really happy with his costume and really acted like Alvin character. His brother join the party too
