Fashion advice from a four year old

The first thing my son asked me when he saw me this morning is:
"Did your sweater shrink?"
When I said no he asked me if I had this sweater from when I was little.
"Maybe did your mom cutted it?"
When I explained to him that this was the style of the sweater he looked perplexed.
"You should wear something else, it won't keep you warm."
Who is this little boy?!
