I wear a t-shirt with my business name/logo printed on it, and jeans. Frequently I wear khaki or other colored (dressier looking but still comfortable jeans!) jeans. I have several t-shirts I made for work, some with a v-neck (not deep!) and some more traditional t's, of varying colors. I also have a few long-sleeved t's that I wear if it is very cold or the work will be very easy, but not very often, as the sleeves get in the way!
My question is what to wear to the presentation I am going to do next Wednesday!!! I want to look dressy, but then I'll do some demo work and need those clothes to comply! Maybe I can dress up my green jeans and get a stretchy dress shirt?
