This casual combination of a black quilted leather field jacket and black chinos is a never-failing option when you need to look cool but have no time to dress up. Bump up the formality of this outfit a bit by finishing off with a pair of black leather chelsea boots. Seeing as temps are getting lower, this outfit appears a viable choice for the transitional season. No doubt, a popular choice if we're talking outfit ideas for 30-year-old gents.
