Izod boys size large 2 piece sweater set. sweater is red, black, and black/white. Undershirt is plaid- red, black, white and just a little bit of green. Undershirt is missing one bottom as pictured. I didn't realize it was missing a button until I was taking these pictures. The button doesn't interfere with the overall appearance as it is the undershirt. Used, good condition .
