Blue is generally a safe color for men to wear. It is fairly easily to style a blue pair of pants. The first look is for a warm weather while the second, cold. Not that they look bad, but there's really nothing new with either. That just won't do for this fashion sensitive Ken.
I was looking for inspiration on how to style a blue bottom when I came across Pause (an online fashion magazine). I forgot what specific article I got the inspiration from, but it was one of those where they feature what actual people wear on the streets. The main trend was a touch of bold colors in men's wear but one guy caught my attention. He was mixing some military inspired pieces with bold colors. It seems like a major mismatch but I kinda liked it and used it in this look. Bold colors seem to make men look softer or feminine but with a touch of a military piece, there seems to be an added masculinity in the look.
