We're big fans of the Mightly brand, especially these basic pieces. I got them in XS (4-5) for my almost 6 year old daughter. She currently wears XS on most other brands. She is 44 inches tall, weighs 40 pounds, is slim and has a 19.5 inch inseam. They fit her legs and length well (they fit perfectly to mid-calf), but are a little baggy in the front below the waist. Most of the time she wears them under longer tops, so that's not a problem. I love that they are made from organic cotton and use minimal packaging. These are lightweight leggings but not too thin to be easily torn or see through. Colors do not fade with washing.
