What decorations do you need for a mermaid party?
You need five core items: a balloon garland, themed cutouts, a “Mermaid” banner, matching tableware and a cake topper. Repeating a single motif across all five is what makes the theme look styled rather than scattered.
What colours should a mermaid party be?
Use turquoise, lavender and silver. Keep to two or three colours and repeat them across balloons, tableware and the banner, so the palette does the theming work.

How much does a mermaid party cost?
Budget $70–160 for 15 guests, or $5–11 per guest. The balloon garland and cutouts take most of the budget; the banner and cake topper cost very little and carry the theme.
Mermaid party food and activity ideas
Serve food in kraft-brown boxes with themed names, and match the cake topper to the tableware. Add one themed activity — a hunt, a craft table or a photo spot — so the decorations also give guests something to do.
