Review on Vibrant Fruit of the Loom Multi Color T Shirts: Boys' X Small Clothing and Tops, Tees, and Shirts by Dino Wilson

My son only likes the white Fruit of the Loom t-shirts. I'm trying to lighten it up so I ordered the same brand and size as his favorite white shirts. They vary in size as shown in the photo. All Fruit of the Loom shirts for boys are oversized, but the ones we usually get in most stores are oversized (14-16) and the ones we've ordered on ebay are oversized (10/12). It is not listed in the size description and based on his measurements (weight 78#, height 59 inches) the size chart shown says he will fit either medium or large. He is 12 years old and thin. He doesn't like showing his stomach when he stretches, that's his test. I'll come back and we'll try the XL. Just note that they may not match the description. I hope they are all the same in other aspects.
