May not be the most controversial topic...but

Is is acceptable to wear brown riding boots with black leggings or jeggings is what some people call them? I've had several people tell me it's ok and some say it's a big no no...lol so ladies, is it still not a thing to do so? I honestly don't care what others think but it's for a job interview. The lady at the boutique helped me pick out an outfit & said it is fine to wear brown with black. Would like some honest opinions. I want this job but I also don't want to look like an idiot!
