A black floral crew-neck t-shirt and green shorts are the kind of a no-brainer off-duty getup that you need when you have no time. If you wish to immediately dress down your getup with one single item, introduce dark brown leather sandals to this outfit. So if it's a warm weather afternoon and you want to look stylish without putting in too much work, this getup will do the job in no time flat. This combo demonstrates that as a 30-something Millennial guy, you have a vast array of dressing options.
