Note: Cuffs do NOT increase the overall inseam. Total inseam stays the same even with cuffs added. They are simply added to the "body" of the pants. If you want to increase the inseam, either through the pant or through the cuff, go to inseam add-on.
Please note that cuff add ons for leggings, SL longies, WL longies and RF schmals are new and in tester mode. That means the size of the cuff could change between orders and that the inseam could run slightly off.
