Decor'(um)
The ambiance should reflect the theme, therefore while decorating your place consider fish nets, treasure chests, anchors, ship models and swords, etc. Keep in mind the standard colors; red, black, white, and gold. These colors can be liberally used in almost all the aspects of the party. While setting the table, if possible use theme-based plates, napkins, and cups and serve beverages in it from flasks.
