Halloween costume ideas for a fiesta party

The easiest Halloween costume ideas for a party come straight from the drink table: margarita glass couples, flavor squads, and cowboys and cowgirls. Build your costume theme around a fiesta, and host on Oct 23 to 25, since our machines are booked out Oct 29 to Nov 2.

A theme makes costumes easier for everyone. Guests know what to aim for, photos look better, and your frozen drink machine becomes part of the decor. Here are ideas for couples, groups, families, and last-minute guests.

Group Halloween costume ideas

Margarita glass couples

One partner dresses as the glass and the other dresses as the rim. The glass wears a pale green outfit with a wide hoop skirt or a cardboard cone. The rim wears white with a sparkly salt sash, or red and orange for Tajín. Add a paper lime wedge headband to finish the look.

Other couple ideas:

• Salt and lime
• Tequila bottle and shot glass
• Piña Colada and a beach umbrella
• Cherry and Limeade, dressed in red and green

Flavor squads

A flavor squad is a group where each person dresses as one flavor color. Pick a set of flavors and assign one to each friend:

• Blue Raspberry: all blue, with blue hair spray
• Mango: bright orange and yellow
• Lime: head-to-toe lime green
• Strawberry: red with seed dots drawn on
• Watermelon: green on the outside, pink in the middle

Line the squad up for a group photo next to the machine, matched to the flavors in the bowls. This idea works for families with kids too, since every flavor comes as a slushie.

Cowboys and cowgirls

Central Texas makes this one easy. Boots, hats, bandanas, and a denim jacket are probably in someone's closet already. Add a sheriff's badge, a toy lasso, or a stick horse for the kids. A western theme pairs well with a classic Lime margarita bowl and a Cherry Limeade slushie bowl.

Costume ideas for kids

Kids love dressing as the drink they plan to order. Try these easy looks:

• Slushie cup. A white T-shirt with a big paper straw taped to the back and a blue or red tutu.
• Lemonade stand. A cardboard box with a hand-drawn sign and paper lemons glued to the front.
• Fruit Punch superhero. A red cape with a fruit logo on the back.
• Little piñata. Rows of tissue paper streamers glued to an old shirt.

Keep kids costumes easy to move in. Kids play games, run around, and spill sticky drinks, so skip anything long or delicate.

Last-minute costume ideas

Some guests show up without a costume. Keep a basket by the door with sombreros, bandanas, fake mustaches, flower crowns, and glow necklaces. Anyone can grab a piece and join the fun.

Plan the drinks around the theme

Our two-bowl machines serve two flavors at once. Match the bowls to your costume theme, or run one slushie bowl for kids and one margarita bowl for adults. Every mix is alcohol-free until you add alcohol, so label each side. Browse all 33 mixes on our flavors page to find colors that match your squad.

Add a rim station for photos. Lime Margarita Salt, Tajín Classic Seasoning, and Chocolate Cocktail Sugar all look great on camera. Each 4 oz package rims about 40 drinks.
