Kan Can denim fits true to size with a lot of stretch! They stretch with their body but don't stretch out. When washed and dried they maintain their shape and size. Inseams vary by style between 26"-31"
Judy Blue denim also has quite a bit of stretch. Many find the waistband has more stretch than KanCan. It is best to stick with the same size as you would in KanCan unless indicated otherwise. Every style fits a little different in both brands.
