I got this thinking that it would probably fit a little small for your average 18 month old, so it should probably fit my small 14 month old fairly well for the winter. She is pretty tiny, about 10th percentile for weight and height. The size 6-18 month is almost too small for her already. The waist is tight, and the ankles leave marks on her legs. The legs also pull up because they're almost too short for her. This is more like a 6-9 month size, overall. The color is also a lot more off-white than I was hoping. I was actually looking for a creamy color to match some of her Hudson Baby dresses, but this was far lighter than I'd hoped for.Other than the size, though, these are super soft and comfy!Great quality, they were super cute and went perfect with the outfit I bought for my daughter!Nice quality leggings for warmth to wear with a dress. We wanted something footless because the baby is learning to walk and prefers to be barefoot. These fit for the age we ordered, but just barely, so go at least one size bigger.Cute little leggings for the price. I like that they don’t have feet, my daughter is learning to walk and it is safer for her to have bare feet :). Also the feet on baby tights are usually so big and weird, so it’s nice to skip that.Perfect little leggings for under dresses. They aren't to thin or to thick and super cute!! Will be buying more!!Perfect alternative to slippery tights with footies. These allow my daughter to have her legs covered and we can still put any shoe on her (or no shoe at all). Fabric is very soft and stretchy. It’s warm but breathable. Will be getting more of these as she grows.These tights are beautiful and fit perfect. But the material is awful. There were cotton balls everywhere after my 5 month old had them on for an hour. Other than that I would have given them a 5 star.Fit great
