A charcoal suede shirt jacket and black skinny jeans are true menswear must-haves if you're planning an off-duty wardrobe that holds to the highest fashion standards. If you want to immediately up this outfit with one single piece, introduce a pair of beige leather chelsea boots to the equation. As you can see here, it's very easy to look sharp and stay comfy when chillier weather hits, all thanks to getups like this one. And if we're talking dressing ideas for men in their 30s, this combination is ideal.
