The tie you choose to accompany a dark green suit can make a statement or balance your outfit. Earth-toned ties in shades of brown, beige, or even muted gold can provide the perfect pairing. However, a deep navy tie can offer a sophisticated contrast when paired with a white shirt under your dark green suit jacket.

For those looking for something more vibrant, ties in rich burgundy or even shades of purple can pop beautifully against the backdrop of a forest green suit. Patterns, such as stripes or florals, can add visual interest, too, without overpowering the suit's color.

A dark green suit can be a stylish choice for a wedding. Its distinctive color offers a refreshing alternative to the more traditional black or navy suit choices commonly seen at these events. Dark green suits are an excellent option for various wedding personnel, including groomsmen, wedding party members, guests, and the groom or marrier themselves.

Keep in mind that the appropriateness of wearing a dark green men's suit to a wedding largely depends on the wedding's theme, venue, and specified dress code. A dark green suit can feel particularly fitting for outdoor weddings, especially those in garden environments, and it can bring some subtle fun to semi-formal or cocktail settings. However, traditional colors might be preferred for more formal or black–tie events.

As always, consider the event and consult the hosts or invitation for guidance on what to wear to a wedding.
