I ordered 2 of these for my tall 2.5 year old. He usually wears 5T, sometimes 4/5. I ordered 4/5 in green and gray. They fit well with some room to grow. I'd say they're a bit big, but not big enough that he can't wear them. We had to roll up the sleeves a bit but the length is good. They have a large neck opening for large toddler heads, so that comes in handy! They should last all winter and spring. They're not as thick as sweatshirts, but heavier than a long-sleeved t-shirt. I would 100% buy more in other colors.
