1. Start with the Base

A great alien look starts with the right outfit foundation.

Go for metallic or holographic fabrics — silver, chrome, or even iridescent green.

A shiny pleated skirt or bodycon dress instantly gives off that out-of-this-world vibe.

You can also use leggings and a cropped jacket if you want something comfortable for trick-or-treating or a night out.


2. Add Statement Accessories

Accessories make the costume.

Space headbands with glittery orbs, silver hoop earrings, or geometric sunglasses all add to that futuristic theme.

If you’re going for a more playful look, throw on a pair of metallic boots or platform sneakers to complete the outfit.


3. Glow from Head to Toe

The “shine” in this look really comes from your light-up and reflective details.

Add glow sticks to your wrists and ankles or wrap small LED string lights around your skirt or sleeves for a subtle glow effect.

Body glitter and highlighter along your collarbones and cheeks give that radiant, cosmic finish.


4. Makeup That Pops

This is where the magic happens. Use metallic eyeshadows in shades of silver, green, and purple to create a galactic eye look.

Add rhinestones or stick-on gems near your temples or around your eyes for sparkle.

Finish with neon lipstick or glitter gloss and a light dusting of body shimmer.

The goal is to glow under party lights while still keeping it cute and wearable.


Final Touches

Complete your look with a fun prop — like a toy space gun or a mini UFO handbag. If you want to go a little extra, spray temporary color in your hair (silver or teal looks amazing) or use clip-in tinsel strands for a celestial shine.

This DIY alien look is playful, affordable, and easy to customize. You’ll look like you came straight from another galaxy — and trust me, everyone will want to know where you got your costume.
