A white and navy long sleeve t-shirt and jeans are absolute staples if you're picking out an off-duty closet that holds to the highest sartorial standards. Beige canvas wedge sandals are a fail-safe footwear style here that's also full of personality. Stick with this one if you're after a cool summery outfit.
This getup with a white and navy long sleeve t-shirt and jeans isn't super hard to score and easy to change. For something more on the classier side to finish off this ensemble, introduce a pair of burgundy leather heeled sandals to the mix. This combination is essentially a lesson in how to dress for super hot summer weather.
