Mens fashion trend nowadays take its cues from the death of the dress code, pairing traditionally with fashion pieces. The key for men is to really know which elements to pick from a dinner suit. The easiest are satin shawl, notched or peaked lapels, or even the satin stripe on the trouser leg.
There are plenty of mens clothing stores where a guy can shop his stuff, and if he's really smart, even in cheap suits or in chic tux, he can create his suave and elegant looks.
I think today men's fashion is not limited to the clothes they wear, but also their entire style. Their hair style and all else is a part of the fashion world of today’s man.
