What do you wear when you exercise?

What do you wear when you go for a light walk or work out at the gym?

In the past, I used to just dress simply and comfortably in shorts and a short-sleeved shirt,

Maybe it's because sportswear comes in such a wide variety these days, haha.

Everyone was dressed nicely while working out.

There seems to be a wide variety of sportswear types and companies as well.

Which sportswear is affordable, comfortable, and easy to wear? Please recommend some!!
