On Halloween, your top priority is capturing a spookin' good pic of your costume, and there's no one you'd rather strike a pose with than your sisters. Before dancing to the "Monster Mash" and enjoying festive beverages, pose, snap, and share on your feed with some Instagram captions for sorority Halloween costumes. Nothing's better than a sister squad moment to kick off such a spooktacular occasion.

If you're unsure of what costume to wear, it might make things easier to plan a group theme. Go as your fave characters from the TV show you and your sisters watch on the reg in the living room. For example, if you marathon-watched Emily in Paris together, consider dressing up in different Emily-inspired outfits from the show. Someone can have a color-coordinated hot pink moment or rock Emily's green jacket outfit, while another sister can channel "Bucket Hat" Emily.

You could be inspired by your favorite actor and give a nod to some of their iconic roles with costumes from different films. Or, keep it simple and go as a coven of witches with bold makeup looks, long tulle skirts, and combat boots.

Whether you dress up together or not, a group pic is inevitable. Be prepared to post right away with any of these 40 Halloween costume Instagram captions. Then, get right back to celebrating All Hallows' Eve with your favorite ghouls.
