As you can see, looking stylish doesn't take that much work. Go for a black vertical striped suit and a yellow silk long sleeve shirt and be sure you'll look awesome. Add black leather oxford shoes to this look to effortlessly turn up the classy factor of this look. Stick with this one if you're hunting for a cool hot weather look. If you're working your way through your mid-20s, take cues from ensembles like this to add more seriousness to your personal style.
