A fall-winter transitional casual men’s blazer 

#FreestyleFridays

First, wear the usual white shirt and matching trousers. Second, cover your shirt with a thick sweater or cardigan. Prefer dark-shaded layers to elevate the white shirt. Over and above, wear a pastel gray woolen blazer with single breasts. Again, add a scarf around your neck to strengthen the layers and completely insulate from the cold weather. 

This might look too much for a few men. In that case, remove one or two items and keep yourself comfortable.
