The thing about stylish menswear is that when it's done right, it seems effortless—the key word being "seems." From fashionable suits to business casual ensembles to weekend outfits with crisp, clean street style, Groupon's ever-changing inventory of men's fashion essentials will help you nail the perfect look without overthinking it.

The Essentials

First things first—it's generally considered polite to wear clothes in public. At work, that might mean business casual or it might mean a suit. Groupon offers office-ready single-breasted jackets and suits by designers such as Verno, and dressy slacks by English Laundry and Alberto Cardinali. But you can't be all business all the time, so keep your closet stocked with more casual men's fashion such as sports sweaters and hoodies, activewear, and heavy outerwear for cold weather.

The Accessories

If you really want your fashion choices to stand out, you've got to go the extra mile with accessories that pop. Of course, a fashionable tie is nearly indispensable (though going without can be a statement of its own), but when your tie needs a makeover, a personalized tie bar and matching cufflinks from Monogram Online will set your style apart. A pair of Tom Ford eyeglasses might inspire envious looks without necessitating formal wear, and designer wallets and money clips prove that men's fashion doesn't stop at the surface level.

The Footwear

They say that clothes make the man, and there's no article of clothing for which that's more true than shoes. Heading to the office? Try a pair of suede oxfords from Adolfo. Have a black-tie affair? You'll need glossy black leather wingtips by Joseph Abboud. When you're out and about in the world, your choices range from K-Swiss sneakers to uber-fashionable Kenneth Cole boots. And finally, a day off just isn't the same if you don't spend it in slippers.
