I got these for my daughter on her 5th birthday. She loves them so much she wore them every day for a week. I had to bribe her to wear something else so I could wash them. I sized up, knowing they may not fit in the waist yet, but the adjustable waistband works perfectly for her. She is a taller, petite kid, so I have a hard time getting the right waist size to length ratio. These are great! I will definitely buy more!
