Both shirts scored at our favorite surfshop in Dana Point, Ca! Quicksilver brown, blue, green and orange plaid button down....size 3T. Apple green Jack's Surfboard shirt size 6. But never mind that sizing. They run small. Very, very small. It would most definitely fit a 3 or 4 year old! Enjoy two of my favorites! Bidding starts at $5. Shipping $3. Happy Bidding!
