When it comes to masculine sophistication, this combination of a black suit and a black and white horizontal striped crew-neck t-shirt is the ultimate style. And if you want to effortlessly play down this outfit with one single item, complement this look with a pair of espadrilles. This look is also ideal if you're in search of summer wear to get through a tedious day. This outfit illustrates that well into your 30s your sartorial options are looking great.
