Where to find Adjustable Waist Pants
I have had great luck with pants from The Children's Place. Most of them have elastic in the waistband that you can tighten as needed, and it then secures on a button. I absolutely love these as Mason is very thin and doesn't usually fit in normal pants. I also purchased a Dapper Snapper toddler belt and use that on pants that don't have an adjustable waist.
