We had to order 3 different sizes (it was a week before his kids promotion so we didn't want to risk it). My son is tall and thin and we usually order a size 8 for him (which fits slightly larger) but his pants were too big. So we ordered 6 and 7 and finally settled on 6. The vest was a bit small but it worked and looked great.
