I personally would give her a less skimpy shirt that is more straight lines and not such complicated folds (just like the one Jack wears, and uhh... boob support? at least if you have that kind of cleavage you'd definitely need one.) I mean she's a pirate queen, that means she'll get involved in some action or another.
It's not an elaborate design to begin with so unless you want to drop all the buttons and maybe her gloves (do pirates wear gloves..? I'd think it's gonna be a bit counterproductive with the salt water) there isn't much to reduce (maybe the hemline of her coat but it's needed for contrast so * shrug emoji *)
I probably would say rather look into getting the shapes more clear-cut and not too bulky, that makes it much easier to quickly draw her. If you haven't quite figured out how folds work, I probably would also leave them out for now unless you go into a detail shot or have a really heavy crease.
It's late now so I won't draw anything rn but I might get back to it in a couple of days when I'm less busy^^
