I also usually have to narrow the width of the crotch area. Most patterns, Kwik Sew especially, are quite wide. Who wants to be fussing with folds of fabric where your legs join your body under your clothes all day? Not me!
I'm really glad I made the pattern because I see this will be a great option for panties once I complete the further alterations I need. I may also consider adapting the Jalie 971 Competition swim suit pattern leg opening to the swim short briefs to make the ideal panty for my body shape.
I cut a 2nd pair of panties in this same fabric using Jan Bones Smoothie Pantie. Once that is complete, I'll share the results of it too. I plan to raise the leg on it before I sew based on what I see I need from the American Hero pair I made.
