Women in Sales: Appropriate Dress Code

Chron.com published the following article on "How to be a good Saleswoman." https://smallbusiness.chron.com/good-saleswoman-25258.html

I was shocked that the very first thing listed was:

Earn respect as a businesswoman by wearing the appropriate clothing. Wear a fitted pant or dress suit in a solid color such as navy, black or gray. Choose skirt lengths that don't rise above the knee or fall past two inches below the knee. Wear short-sleeved or long-sleeved shirts; never sleeveless or spaghetti string tops. Keep jewelry to a minimum, and wear your hair in a classic hairstyle such as a sleek ponytail or bun. Finish the outfit with closed toe shoes at a medium heel height.

This form of thinking is outdated and obsolete in most industries, but especially in Sales. Women in sales should be able to express themselves in colors other than navy, black or gray.

Here is another example of a corporate dress code that is more reasonable https://www.boehringer-ingelheim.us/sites/us/files/fs_guidelines_for_dress_and_appearance.pdf

Given the global pandemic - WHAT do you consider appropriate? Do you get dressed for work or are you more casual in a t-shirt and jeans with a ponytail.
