UPDATE May 2018 We have two pairs of holes as my daughter is very active on the playground. The waist is stretched a bit and I'm considering tucking it in at the sides. Although I also think she has outgrown them as she turns 6 this month and I need to go up for fall. UPDATE September 2018: My daughter is now too big for her. She is in the 1st grade. It also seems that the rubber band has lost its elasticity. We no longer use. ========================= My daughter goes to kindergarten and wears a uniform with navy blue tights four days a week. We hope 6 pairs will last the whole school year if we wear each pair once a week. Fits perfectly. She has room to grow. She wears 5 kids leggings and pants so we have an average age of 4-6 years. She noted they were soft, but the label was itchy. Let me know if you have any questions and I'll tell you how long they take.
