Under the sea birthday invitations

Choose from a wide range of under the sea invitation templates to match the theme of your little one’s birthday party. Whether you’re looking for something beautifully minimal, or a template to catch the eye of your guests, we’ve got something to suit every birthday bash.

When to send your ocean-themed birthday invitations

You should aim to send out your ocean birthday invitations between five and six weeks before the big day, in order to give your guests ample time to read and respond to them. You can send handy reminders to those who have opened your invite but haven’t yet RSVP’ed.

What to write in your under the sea invitations

Make sure to include the date, time, and location of the event on your kids’ birthday invitations. Add details of a dress code, if there is one, for example, ‘Fishy Festivities’, ‘Sharks and Shellfish’, or ‘Mermaid Magic’. You’ll also want to include a deadline for RSVPs so that your guests know when they need to respond.

Decorations for your under the sea birthday party

Decorate your table with beautifully illustrated under the sea plates, fish napkins, party cups, and watercolor clamshell plates to serve your food or snacks. With both under the sea and mermaid party supplies available, there are plenty of options to choose from!

Embellish your party venue with blue balloons and streamers to give the space the feeling of an under the sea paradise. Invest in mermaid foil balloons and fringe garlands to give your little mermaid the birthday bash of their dreams.

Encourage some under the sea games and activities with mermaid tattoos and mermaid pinatas. Give your guests some fun party bags filled with mermaid pinata favors so they can keep the party going once they get home!
