These pants run at least 1-2 sizes larger than older pants of the same style. I've compared them to the 2016 2T I bought from Carters and the 3T I just bought from Amzn is more like a 4T in terms of waist and length. I've noticed that Carter's has expanded their sizing options and no longer trusts their fit recommendations. My kids are average height so sizing shouldn't be that wrong. I will always downsize in their brand. I sew children's pants similar to this style and compared to several sewing patterns, this fit is definitely at least 2 sizes larger in waist and length - I've never had to make large adjustments to size while sewing and have found patterns for 2T, -5y. I agree. I'm concerned about the sizing inaccuracy and they even use weight as a guide. I bought these to replace 2Ts that have already gone through 1 child and due to their french terry fabric they last longer than other pairs and wash very well.
