What do you wear to mass?

I converted in April. I have gone back and forth as to what is appropriate to wear to mass. When I was a kid people tended to dress up for church, now i see track suits, shorts, and all sorts of things, and very few if any women cover their hair. I do wear a scarf now for mass as that is appropriate because i feel I am in the presence of Jesus. I tend to wear long skirts or plain pants and a top. What do you wear?
