A multi colored horizontal striped polo and a grey suit are absolute essentials if you're crafting a sophisticated wardrobe that matches up to the highest menswear standards. A pair of white and navy athletic shoes easily revs up the wow factor of this ensemble. This combo isn't a hard one to score and it's summer-appropriate, which is most important when it's roasting hot outside. And if we're talking dressing ideas for gentlemen in their thirties, this outfit looks cool on most men.
