Boys Size 3-5 Surf Rash Guard and Shorts Set

White rash guard with surf logo. Red shorts with sailboat pattern. I purchased these from a boutique. I paid $79 for the shirt and $59 for the swim trunks. The shirt says size 6 it runs very small. Our grandson worked when this past summer and he’s a size 6, and it was a little small on him, but he loved the shirt so much he didn’t care. Swim trunks say they are size 3 to 5. I would say both of these would fit any child from age 4 to 5 years old, you might could get a two years use out of them. My grandson is tall and slim.
