Plus Size Halloween Costume Ideas

Before getting into the FABULOUS plus size Halloween costume ideas, there are a few tips I want to share with you:

Tip #1: Many of these costumes are DIY friendly! I’m a big fan of sourcing accessories and using clothes you already have!
Tip #2: Add fleece tights for warmth! I’m in Utah, and it sometimes SNOWS on Halloween (ugh). Adding in fleece tights to a, shall we say, more revealing (ahem) costume still keeps the vibe, without freezing my butt off, lol!
Tip #3: Get a tote for your costumes! If you’re anything like me, then you have had a LOT of costumes over the years. The accessories and items for a costume seem to get scattered to the four winds by November 5, so I def recommend getting a Halloween costume storage cube set!

Alrighty, are you ready to talk all things plus size Halloween costume ideas?! Then let’s get TO IT!
