The grooms wedding attire can be of various styles- the first one should influence your taste. You can wear something that is totally different from the rest of the crowd present at the wedding. However, you must be open to experiments for that matter. You can match up the color of the tuxedo in cowboy style with that of the bride. For instance wear a white western wedding tuxedo with white shirt. Complete the look with matching shoes and tie. If you are not in favor of going all matching- matching with the bride, you have a different option. Tuxedos in cowboy style are quite in fashion among modern men. Wear the suit in two piece style with just the jacket and trouser with a shirt or you can get the three piece tuxedo look. If you want to get the traditional look you can wear this tuxedo with a vest. The western tuxedo vest gives you a smart look by giving your body a proper shape.
If you want a relaxed look for the wedding tries out wearing a tuxedo without the vest. There is no harm in going for this look. Wear black mens suits with contrast bow tie and black formal shoes. This will give you a tuxedo like the look, but in a suit. If you are having a garden wedding, a mens tux with white dinner jacket and black trouser is a classic choice. On the other hand, if your wedding is a romantic dinner sport a tuxedo in cowboy style with a tail and bow tie.
