Ties are especially elegant for black tie and formal occasions. This is the perfect accessory to tie up your look as the right tie will make a shirt, a blazer or a suit look even more refined and sophisticated. If you really want to make a killer impression you can tie a Windsor knot, a half-Windsor knot, an Eldredge knot or a double cross knot. The bow tie isn't what your nerdy cousin used to wear at Christmas. The modern variety comes in all shapes and sizes, from skinny to oversize, to prints and casual fabrics such as wool and flannel.
