You'll be amazed at how super easy it is for any man to get dressed this way. Just a white v-neck t-shirt paired with grey jeans. Add brown suede desert boots to the mix to change things up a bit. So if it's an extremely hot warm weather afternoon and you want to look on-trend without putting too much effort, this getup will do the job in no time flat. Now that's how you keep it casual as a 30-something gent.
