Our costume fit size chart breaks it all down with real measurements, so you get the size that suits your curves and your confidence. If you’re between sizes, it’s better to size up for maximum comfort.
Neckline and Sleeves
Necklines and sleeves set the tone; these are the details that frame your whole Halloween outfit.
A turtleneck gives sleek, futuristic energy, while a mock neck keeps things clean and quietly bold.
Long sleeves bring strong silhouettes and a sense of presence. Sleeveless styles and fingerloops add movement, mystique, and a little bit of magic. And if you’re here for full drama, trail sleeves are made to leave a lasting impression.

How To Style Your Blue Costume for Halloween?
Blue brings the drama, but it’s how you style it that makes it unforgettable.
If you’re channeling a sea siren or a cosmic queen, here’s how to make your blue Halloween costume hit harder:
- Go full glow with neon or UV-reactive pieces - perfect for after-dark parties or haunted raves. Pair them with metallic boots, chrome nails, and glowing face gems for a look that’s out of this world.
- Leaning into a fantasy theme? Start with a blue catsuit or dress, then layer on a sheer cape, silver eyeliner, and holographic wings. Add ice-toned hair or a wig to turn up the otherworldly vibes.
- For an underwater-inspired look, go mermaid mode. Level-up your blue full-body costume with shimmering scales, wet-look waves, and shell accessories. Add body glitter, sea-blue mascara, and strappy heels to make it glam.
- Futuristic is more of your thing? Choose sharp, graphic prints in electric blue. Style with mirror shades, platform boots, and sleek hair for a villain-core finish that commands attention.
Whatever your take - mythical, cyber, celestial - blue gives you the range. Just pick your vibe and run with it. Halloween only happens once a year. Make it look like it’s from another world.
