As Separates

A khaki suit is also incredibly proficient at working overtime and being split into separates. Whether it’s the top or bottom, the neutral shade can break free from its suited shackles and be let loose alongside everything from a check shirt to a coloured blazer to a varsity jacket.
For example, you could ditch the matching suit jacket for a Riviera blue blazer or a more daring red equivalent with very little thought, yet the change would make a enormous difference to the overall complexion of the look.
If your looking to make a more casual statement, pair the suit trousers with a casual shirt with the sleeves rolled up or even a t-shirt and cardigan combo. There is no reason why a good pair of suit trousers in a flattering fit can’t serve double-time as a casual option, especially in a cool cotton or linen weave.
On the flipside the jacket part of the suit has a similar amount of versatility, although a blazer will always carry a smarter element than the trousers. You could quite easily pair the jacket alongside some coloured chinos, alternative neutral coloured trousers or even some shorts for a cooler summer suited outfit.
