The T-shirt is great quality! The cotton is thick and does not lose its shape. I bought this as a gift last Christmas and since then it has been washed many times and I haven't seen any stretching or tears. The size fits perfectly. The printing is excellent. The colours and the design were exactly as shown in the picture. One year after, it hasn't faded due to washing.
