You wrote your love in the stars—so why not feature them on your invitations? Pro tip: Incorporate your zodiac signs and birth charts for a more personalized set. Create a wow-worthy ceremony (or reception) setting by decorating the space with gold stars suspended from the ceiling. Use stars in varying sizes and string them up with a fishing line for the most realistic effect—it's even more magical when you add candles.

Create A Lunar Invitation Suite

This invitation suite features a mystical lunar motif. We especially love the speckled galaxy design going on here. If you have the budget, you can also include a small crystal per invite—a token your guests will surely appreciate! While there's always the option of sending out invitations decorated with stars and glitter, we prefer a more subtle take on the celestial wedding theme when it comes to your stationery. These navy blue invitations are the perfect example of how to pull off a galactic-inspired theme in a unique way with details like constellation sketches, whimsical calligraphy, and watercolour paper.

A celestial wedding theme is all about incorporating whimsical details, and that goes for your wedding day attire, too! Rock a wedding dress covered in starburst-shaped beading or sequins (like the "Orion" dress by Willowby, shown above) to make a statement true.  

Achieve an angelic, out-of-this-world glow by keeping your wedding day makeup light and airy. First, focus on using products that aren't overly matte, then amp up the shimmer with a highlighter on your cheekbones, metallic eyeshadow or eyeliner, and high-shine lip gloss.

Celestial wedding decor can be as lavish or as subtle as you prefer. If you're committed to nailing the aesthetic, though, we recommend a statement sign inspired by the theme—and this "To The Stars" rendition is a great fit.

Shades of blue are a colour palette must-have for your astrology-themed wedding. And, if you won't be wearing a wedding dress, consider a luxe velvet midnight blue suit to give your outfit a thematic finish.

Crystal Centerpieces

The way you arrange your wedding reception tablescapes will leave a lasting impression on guests, and we love the rich texture and dimension these crystals bring to the table. Plus, polished geodes are an easy way to add something special to your place settings in shades that correspond to your core wedding colours.

Invite your guests to go "stargazing" inside your wedding venue by suspending large statement stars from the ceiling. We feel a decorative accent like this will focus on so many Instagram stories throughout the evening.

Zodiac Table Numbers

This celestial wedding decoration is an absolute must if you're an encyclopedia of zodiac sign meanings. Instead of categorizing tables by numbers, give them different zodiac signs instead. And, for an added touch of personalization, consider leaving small cards of different facts about each zodiac sign on the table for guests to read. (They might even want to take it home as a wedding favour.)

Starry Accessories

Bring a pretty pop of sparkle to your zodiac wedding day attire with a few starry accessories, like hair clips or statement earrings.

Blue Bouquet

Work with your florist to build a celestial wedding bouquet featuring in-season blooms. We recommend using flowers in deep shades of blue, indigo and purple.

Sky Blue Suit

If a dark blue suit or tux isn't your thing, try switching it up with a pastel shade instead. This bright colour will complement your S.O.'s outfit to create a unique celestial look.

Constellation Vow Books

While a vow book isn't necessary for your wedding ceremony, it adds a sentimental touch. Matching vow books with constellation prints is a super simple way to honour the theme if you're looking for unique celestial wedding theme ideas.
