I like the look of slacks, dress shirt, with or without a tie, and a vest. Since I don't have a three piece suit where I can just ditch the jacket, I was wondering if I can achieve this look nicely using an odd vest. I was interested in a charcoal wool vest with subtle narrow striping (alternating black and dark brown stripes) which has, a black rayon back, with adjustable back belt. The pattern somewhat resembles herringbone as there is texture between the lines, but it's not. I believe the vest has matching trousers but I don't care for the fit of those. Can I use this type of vest with different slacks? If so, what color slacks do you think would look good (different shades of gray or brown, navy, black??), and can the slacks have patterns, like herringbone? Thanks for the suggestions.
