Casual
Joggers can be styled casually with a well fitted, crew cut black t-shirt or a white t-shirt depending on the colour of the joggers. If you want an understated look, wear a trainer. If you want a vibrant look, go for prints and patterns, but don't get too much of it, it'll end up being messy.
Formal shirts
Shirts have its own advantages. Shirts can pull off any look. The sleeves can be rolled up, rolled down, open, buttoned, half-buttoned, there are options for anyone and everyone. With joggers, you can complete the look with half shirt properly colour coordinated. You can finish off the look with some neutral plimsolls or a pair of boat shoes. If you want to add some accessories, you can wear a cap to complete the look.
