I've been buying one size up for three years now. They are expensive but of good quality. I had my eye on the green but only bought it this year. Rather disappointed. It is lighter than forest green and has an odd shade of green. We also have gray and black, which I really like. I love how thin they are. My little one is tall and skinny and they always fit so well. He is 37 inches and 31 pounds at 3.5 years old. 2T is ridiculously small, but he still loves them as pajamas. 3T fits well and 4T fits well too with room to grow.
