While scouring the internet I came across this image of this gentleman in an olive green suit. And as much as his complexion and skin tone complement the colour, the final outcome is rather dull considering the olive green tie, the dark blue shirt and the nondescript pocket square. I have learned that when it comes to a colour like olive the brighter the accessories the more congruent the final look will be. A white shirt deserves much consideration because it contrasts well and works with many other neutral colours. Consider other colours that complement other shades of green. I think an orange knit tie would've contrasted perfectly with the dark blue shirt. A patterned shirt would be a great addition especially because it would break the monotonous green; I suggest a gingham pink or a blue and white candy stripe shirt, they could do the trick. However, I'm inclined to think that various shades of blue could be a starting point when it comes to a shirt.
However there are some features to appreciate about this suit; It's got patch pockets including the breast pocket, the visible lack of belt loops indicates that the trousers have side tabs, the jacket also has a 3-roll-2 button stance, and I surmise a double vent.
