My daughter is 6.5 years old, and I ordered the size 6–7 years. I LOVE the way it fits her! I can tell these jeans will last her another 1–2 years, which is a big plus in my book. They fit snugly around the waist and are perfectly loose around the legs, making them breathable and easy to move in. You can easily dress them up or down with different outfits. I hope these jeans never phase out.
