I suspect a showdown could be headed my way at work. The dress code requires "dress pants", which to the management team means 'pants with a button zip fly'. They mostly wear chinos and khakis, straight leg (very Casual Friday, if you ask me).
I have a few pairs of pants that have hidden zippers on the side or rear seam. Like, JCrew slim leg pants and a pair of slim straight Lafayette 148 pants in a khaki color. I also have a pair of skinny leg black velvet pants from Gap that do have a button and zip. Today, I'm wearing a khaki colored pair of slim straight chinos. IMO, the Lafayette 148 and JCrew pants are almost more business formal, but I'm not a stylist or any other sort of fashion/style professional.
Ultimately, I would like to get some information from a subject matter expert (which includes all of you fabbers, too). What makes a dress pant a dress pant? Are my hidden zipper pants dress pants? I know a velvet skinny from Gap is open to interpretation, so I get it if I have to take those out of work rotation. The others 2 pairs, what say you experts?
