Unique Halloween Party Theme Ideas for Adults

Halloween parties aren't just for kids! But it can be tricky finding the right mix of scary and festive when it comes to choosing your theme and Halloween party decor, especially without being too childish or hokey.

This article will share some of our favorite adult Halloween party themes and decorations for All Hallows' Eve and show you how you can include DIY Halloween florals for a spooktacular soirée.

Creative Adult Halloween Party Themes

If you want the best adult Halloween party decorations, you need to get a little creative. Halloween party decorations don't have to be expensive or over the top to make a big impact. And when you include Halloween floral decor, you'll create a party to remember.

Here are some of our favorite adult Halloween party themes that are age-appropriate and easy to execute.

Black-on-Black Adult Halloween Party Decorations

An all-black adult Halloween party theme paired with sophisticated Halloween party decor is très chic and really sets the mood for a cool and classy Halloween dinner party. Black cats, pumpkins, linens, feathers and vases, crows, bats, spiders and spooky Halloween trees are just some of the ways to create the foreboding mood. Add a luxe touch with gilded candelabras, smoking cauldrons and elegant Halloween outfits.

Maleficent Halloween Party Theme Ideas

Deck the halls with a variety of green and purple Halloween party decor to create an homage to Disney's terrifying villainess.

Recreate her haunted forest by covering the ceiling in spooky black material adorned with trailing fake vines and crows. An ornate golden mirror can be hung as the focal point of the main room. Add black, green and purple Halloween lights and provide fake crowns for your guest. "Poison" candied apples and goblets for beverages complete the party theme.

Spooky Spiders Adult Halloween Party Theme

This one's definitely not for the arachnophobes in your group, but spiders are one of the classic Halloween themes for adults that always cause a stir. Creating a terrifying display is very simple: just hang lots of fake webs and place spiders everywhere! If you want to really go big, add a giant spider to the front of your house or strategically placed topiary.

Pumpkin Patch Halloween Party Decorations for Adults

Halloween parties don't have to be spooky. If you prefer a fall theme, artificial flowers and decor create a cozy vibe. Pumpkins are a fall classic and can be incorporated into many Halloween party theme ideas for adults, but recreating a pumpkin patch is one of the easiest Halloween party theme ideas. Simply fill your party space with pumpkins and gourds of every shape, size and variety! At Silks are Forever, we have a wide variety of pumpkins that go well beyond what you'll find at your typical pumpkin patch, including:

• Sequins

• Velvet

• Metallic

• Plaid

• Burlap

• Beaded

• Knitted

Add some sunflowers, corn stalks, fall wreaths and festive signs to complete your Halloween party decor.

Day of the Dead Halloween Party Theme Ideas for Adults

Día de los Muertos is always one of the most popular adult Halloween party themes. There are many ways to incorporate florals into your Halloween party decor for this theme. Marigolds (cempasúchil) are the iconic flower associated with the Day of the Dead, but you don't have to limit yourself to this one type of flower.

• Fill a skull with blood-red roses and greenery to emulate La Catrina's elegant skeletal style and place it on a table covered in black lace.

• Fashion floral crowns out of roses, marigolds and chrysanthemums to complement your sugar skull makeup or to be used as decor.

• Create your bar in the style of a cempasúchil altar. Include candles, mezcal or tequila, family photos and sugar skulls.

• Arrange bouquets in shades of purple, pink, red, white, orange and yellow for female guests or to be used as Halloween party decorations.
