Mermaid Lagoon
Mermaid Lagoon parties continue to sparkle this year but with more iridescent details than before.

Others gravitate toward themes with a little more edge. A Kuromi Kawaii Bash blends sweet and edgy with a palette of black, lavender, and hot pink. Bead stations for making pastel and black bracelets keep hands busy, while cupcakes topped with Kuromi ears make the table pop. It’s playful but with just enough cool factor to feel different.
