Little Boy's Under Armour Set

This is a matching set but my son has a normal size torso and a teeny tiny waist so I had to buy him his regular size shirt but smaller size shorts. The shirt is in perfect condition. The shorts have two very small "stains" on the front, near the crotch seam. The color is a neon green. Selling as a set but since the sizing aren't both the same I am willing to sell the shirt and shorts separately. $20 for the matching set OR $10 for just the shirt and $10 for just the shorts.
