Sometimes going with suit separates are the way to go. And what I mean by separates is not wearing the whole suit as a unit like the matching jacket, pants, and sometimes vest.
And for many of us big guys that's the best way to go. Sometimes your chest is bigger then the corresponding pants that come with the suit and if you don't have the means to get suit made-to-measure then suit separates would be a perfect fit for you.
So take this look for example. Because the pants to this suit aren't fitting at the moment lol. I paired the blazer and vest with a coordinating pair of navy blue pinstripe pants. By mixing up your suits and playing around with the separates it's a sure way to create some interest with your style and give you a more contemporary look.
