Wide belts that were in style back in the day are definitely coming back in style. You can wear them with all kinds of stuff, too. Wear them with jeans over a snug sweater, or wear them with leggings and a long shirt.
Wide belts were a bit more popular a couple years ago than they are now but you can definitely still get away with wearing them. Many of them are very fashionable depending on what you wear them with.
Wide belts are indeed back. especially multi color ones with patterns. wear them with your favorite skinny jeans or I suggest you wear them over with your favorite casual dress.
