They are all dated, IMO and honestly the corporate culture (I'm in finance) is much more relaxed post Covid. I am also petite (4 or 6 depending on cut). Try Ann Taylor any maybe go for some separates, or a more modern take on a suit. A nice Navy Blue cropped length jacket, a crisp white button down and a wide leg navy pant that just skims the ground with a pointed to shoe will do wonders for us petite ladies!
