Bringing patterns to a stylish harmony throughout a men’s suit can be difficult. Here we have a Summer green Scabal jacket, RL Purple Label multi-colored striped shirt, floral print silk Etro square and orange Tom Ford knit tie. This ensemble works because each piece is connected by tone not a specific color.
The burnt orange tie pops amidst the hunter green jacket with a bit of more orange on the handkerchief. Stark white on the collar also serves as an ice breaker to not overpower the eyes with flowing stripes.
Remember the goal of combining multiple color elements is balance. If it looks like too much is going on then you are doing it wrong.
