My son fits a size 3T with a narrow waist. I ordered 3t. Pants fit like most 3T pants - good length, wide waistband. I could tighten them up a bit. The shirt fitted perfectly. However, the jacket is huge. WAY too big. I don't know how this would fit any child in a size 3T! So disappointed. The material isn't the best, but that doesn't bother me. He would only wear it twice. Everything was right except for the unusually large jacket. Will have to return. So disappointed.
