Do you need to spend money on style/beauty for your job?

Hi all! The reason I ask is because my role is mostly internal-facing, but I recently needed to support a work event. When I showed up, I realized the rest of my team (all women) all had perfect colored nails.

I also once heard that a major organization in my area paid for a stylist and new wardrobe for their new president (a woman).

So: do you need to spend money on beauty for your job? If so, what industry are you in? Are these expectations explicit or unspoken? Are you reimbursed for any of this? Do you feel as if you are held to a higher standard than your male colleagues (for this specific criteria)?

Would love to hear your thoughts in general, responding to my specific questions is totally optional!
