Beach Costumes

One of the main activities of Halloween is dressing up, and it’s not just for kids but for adults, too. Since you’ll be throwing a beach-themed Halloween party, choosing the right costume is important. Below are a few creative beach costumes perfect for a seaside celebration. 


Transform into mythical sea creatures this Halloween season with shimmering scales, seashell accessories, and tridents. Draped in enchanting merpeople costumes, you’ll feel like you’ve emerged from the depths of the ocean to join the festivities. These costumes capture the essence of the ocean, and you’ll be sure to make a splash at your beachside party. 


Plus, you can pair your merperson costume with some subtle big BOO earrings for fun. 


You’ll be singing “It’s a Pirate’s Life for Me” and “Yo Ho, Ho” around the bonfire when you choose a pirate as your beach costume. Pirates are notorious for being out at sea. It would be feasible for them to wind up at a beachside shindig if given the opportunity, especially if there’s free food involved. Give your pirate costume a true beach twist by wearing flip-flops or tropical shirts. 


There are plenty of beach-themed animals you can dress up as during your beach-themed Halloween party. You can channel the playful spirit of seagulls, wearing feathers over a chic orange swimsuit and a beak-shaped mask. Or you can scuttle around the sandy shores with oversized pincers and a shell-adorned outfit. If you want something more ethereal, opt for a starfish with flowing arms. 

Tropical Fruit

Beach costumes wouldn’t be complete without tropical fruit-inspired outfits. As a pineapple, you can wear a spiky headpiece that exudes zesty charm. Or you can dress up as a coconut, complete with a straw hat to add a touch of island flair to your costume. 

Beach Decor

Once you have your costume picked out, the next step is to think about how you want to decorate your event. Halloween events should have an air of spookiness, but since you’re at the beach, you also want an unmistakable beachside vibe, so getting the perfect blend is important.

  • Seashell and seaweed garlands: Hang garlands made of seashells and artificial seaweed to create an eerie underwater effect. These garlands will bring about feelings of a mystical underwater realm while also casting haunting shadows when dim, flickering lights hit them just right.
  • Glow-in-the-dark beach balls: Place glow-in-the-dark beach balls around your party area for a functional and stylish beachy feel. Toss them around as an activity or just admire their eerie glow from the side as you stand around in your beach costume. Either way, they will add a touch of whimsical to your spooky beach party. 
  • Tiki torches with spooky accents: Having the right lighting is essential to any event. For beach-themed parties in particular, it’s fun to have tiki torches, and you can add spooky accents, such as fake cobwebs and witch hats, to give them a Halloween twist. 
  • Sandcastle centerpieces: You’re at the beach, so having sandcastles is a must. Create mini sandcastles as centerpieces and place tiny pumpkins or ghostly figurines around them for a spooky effect. 
  • Graveyard accents: Allow your guests to walk through a fake graveyard scene in their beach costumes. Use driftwood to create tombstones and arrange them on the beach. Pair your graveyard accents with light up glass pumpkins for an even spookier vibe.
