It's getting to be that time of year again: Halloween wedding season! We can always count on seeing loads of weddings where guests are encouraged to come in costume. Because, seriously, costumes always amp up the fun factor. Here are 18 weddings that totally get it right when it comes to rocking the costumes.

Oh, and if you need some help getting your guests excited about donning some garb, here are some tips.

The appropriately named "Team Awesome" gives new meaning to epic commitment (and heels).

Oh, and providing killer masks helps, too!

Pirates, baby - the best way to show off your floofy shirts that you know you totally own.

A steampunk costume theme is the most reliable way to confuse... and then ultimately delight your guests.

One signature costume (like a Beetlejuice officiant!) can set the mood for the whole shebang.

Costumes at festivals are a given, so when weddings adopt that theme, it can be amazing.

Ye olde ren faire-style is one of my personal faves.

Don't forget Viking weddings! These look era-appropriate and comfy.

No wedding dress code can fail when Buttercup and Wesley are the anchors.

Lightsabers make every Star Wars theme better... as does Waldo, right?

A fairy tale theme is the best of all worlds: totally open, understandable, and Shrek-able.

Plus, we got to see this fabulous hooded gown!

Masquerades are (appropriately) all about the masks, so dressing guests (and this dapper wedding party) is easy-peasy.

Raise your hand if you're planning a costume and/or Halloween wedding!
