My DIY attempts typically consists of (1a) folding the excess fabric under to around the ankles or (1b) higher for a cropped look, (2a) rolling it up messily above my shoes, (2b) neatly folding for the cuffed look, or (3) leaving as-is for the scrunched look.
I'd say (1a) is probably my go-to look. With new pants it's kind of a pain because there are no prior creases from previous folds, so it takes a bit of trial and error to line up both legs evenly. (2b) is one that I don't wear often and today is the perfect opportunity to change that. Unless you look closely, the cuffs are barely visible with black pants. I don't know why I haven't tried this sooner, but this look is slowly growing on me. As the saying goes, there's a first time for everything.
