This is a nice boys button up shirt from the Children's Place, size large 10/12. My son picked it out for picture day for school and it was really cute on him. It can be dressed up and tucked in, or left open with an undershirt. There are greens and blues that make other colors in the plaid mixed with white. It has one pocket on the upper left of the chest. The measurement from armpit to armpit is 16.5 inches, and the length from the top of the shoulder to the bottom of the shirt is 25 inches. Non-smoking home, but I do have pets.
