This - some people have themes but not everyone, and I don't think I've been to a single wedding lately that had a real "theme." Just have a general idea of the colors and what kind of decor/style you'd want, and go from there.
These were my original wedding colors but my wedding is in April so I changed the gold to rose gold and the burgundy to lavender. Either way it’s a beautiful palette on it own. Maybe like someone said glam, elegant, formal.
