To put together an off-duty ensemble with a modern finish, you can easily rock a white and blue vertical striped long sleeve shirt and white chinos. And if you want to instantly up the style ante of this getup with a pair of shoes, why not introduce dark brown suede loafers to the equation? As the weather is getting warmer, it's time to get rid of those heavy winter clothes and choose an ensemble that's lighter, like this one here. Dressier combos like this work well on 30-year-olds.
