I absolutely love these trousers for my super petite nearly 4yr old. Theyve just gone into 2yr clothing but i cannot find school trousers in that size at all. I purchased 3yrs. These are slim fit but plenty of stretch, adjustable waist with button and zip and so soft and they wash so well. These are my second lot of purchase (i only bought one pair to try out at first) there is minimal wear on the ones shes had for last 8month and still look in great condition so bought more for each day of the week. Id very highly recommend these. Well worth it!
