A semblance of protection from the sun
Hats. I used to just ignore it but about three or four years ago, I got hooked to it! Nothing fancy, mind you. Just the kind of hats that I can use whenever I go out. Golf hats, beach hats, and some that I used in fancy events I went to like weddings, conventions, and reunions. I kept most of the hats and use some of it whenever I go out and I need a semblance of protection from the sun, aside from my sunscreen protection, that is.
I am not too much of a fussy dresser but when I feel like it, I really dress up. When I have big meetings, I make sure to dress carefully so as to leave a good impression. We all know how most first impressions are based on the outside appearance of the person, right? I want to leave a good first impression so as to get more clients.
If I have to meet someone for business outside and the sun is shining down, I make use of my hats.
