Costume ideas for theme parties year round
Costume ideas for theme parties all year: fiesta, tiki, and Texas looks, flavor squad group costumes, couples ideas, and easy kids outfits for any party.

The best theme party costume ideas are easy to put together from your closet, match the party's drinks, and work in the heat. Use the ideas below for a fiesta, a tiki night, a Texas party, or a flavor squad group costume, any time of year.
Keep costumes simple. Guests should be able to sit, dance, play games, and hold a frozen drink without fuss. Put the theme on the invitation with one or two examples, and say costumes are optional.
Fiesta party costumes
A fiesta is all about color. Build looks around bright florals and bold stripes.
- Flower crowns in red, orange, and pink
- Embroidered tops or dresses
- Guayabera-style shirts or bright button-downs
- Papel picado colors in a solid shirt and contrasting scarf
Celebrate the culture rather than caricature it. Skip fake mustaches, ponchos worn as a joke, and anything that turns a culture into a costume. Bright clothes and a big smile are plenty.
Drink match: Lime and Strawberry margaritas, or Mango and Pineapple for a sunny orange and yellow look.
Tiki and tropical costumes
Tiki parties are easy for everyone, and the outfits stay cool on hot days.
- Hawaiian shirts and flowered sundresses
- Leis for every guest at the door
- Straw hats and sunglasses
- Grass skirts worn over shorts
Drink match: Piña Colada and Mai Tai, or Blue Hawaiian and Hurricane for a bold blue and red pair.
Texas party costumes
A Texas theme works for birthdays, reunions, and game days.
- Cowboy boots and jeans
- Western hats and bandanas
- Pearl snap shirts in plaid or denim
- Rodeo queen looks with sashes and sparkle
- Burnt orange or maroon for a college game day crowd
Drink match: Lime margarita in one bowl and Cherry Limeade or Watermelon in the other.
Flavor squad group costumes
A flavor squad dresses as the flavors in your machine. Each person picks one flavor and wears its colors.
| Flavor | Costume colors | Easy props |
|---|---|---|
| Lime | Lime green and white | Lime slice sunglasses |
| Strawberry | Red with white dots | Green leaf headband |
| Blue Raspberry | Bright blue | Blue wig |
| Mango | Orange and gold | Fruit hat |
| Frosé | Blush pink | Pink sunglasses |
| Piña Colada | White and yellow | Paper umbrella pin |
| Green Sour Apple | Neon green | Apple sticker |
Squads look great lined up next to the machine for a group photo. Award a prize for the best squad. See the full list of 33 mixes on our flavors page for more ideas.
Couples costume ideas
Two-bowl machines pour two flavors at once, which makes pairs easy.
- Lime and Salt: one in green, one in white with a "salt" sign
- Strawberry and Banana: red and yellow for a Strawberry Banana duo
- Piña and Colada: one dressed as a pineapple, one in coconut white
- Peach and Bellini: a peach outfit and a sparkly gold one
- Cherry and Limeade: red and green, side by side
Couples can hold matching cups from each bowl for photos.
Kids costume ideas
Kids love costumes they can run and play in.
- Slushie cup: a bright T-shirt with a paper straw taped to a headband
- Superhero in their favorite flavor color: a blue cape for Blue Raspberry, a red one for Cherry Bomb
- Little cowpoke: boots, a bandana, and a stick horse
- Tiki kid: a lei and a flowered shirt
- Fruit costumes: a strawberry, a watermelon, or an orange
Skip masks for small kids when you can. Face paint or a hat lets them see clearly while they play. Every mix is alcohol-free until you add alcohol, so a kids costume parade ends nicely at the slushie side. Label each bowl when one holds a margarita.
Make costumes part of the party
- Costume runway: clear a path, play music, and let every guest strut.
- Awards: best squad, best couple, best homemade, and best kids costume.
- Photo spot: set up a backdrop near the machine. Our decorations guide shows you how.

Questions
What should I wear to a fiesta party?
Wear bright colors, florals, and comfortable shoes. A flower crown, a colorful shirt, or an embroidered top works well, and you can skip anything that makes fun of a culture.
What is a flavor squad costume?
A flavor squad is a group that dresses as the flavors in the machine. Each person wears the color of one flavor, like green for Lime or red for Strawberry, and the group stands together for photos.
How do I add a costume theme to my invitation?
Put the theme and one or two examples on the invite, like Tiki night: Hawaiian shirts and leis welcome. Say that costumes are optional so no one feels left out.
