New costumes, new accessories, new makeup - Halloween revolves around all things new. While it may be fun, purchasing new outfits year-in, year-out in the name of a single soirée is undeniably wasteful. Sure, it makes for a great Instagram post.

In the long run however, it’s far from being sustainable. Plus, it can be a lot of effort to throw together an outfit for one night and one night only, especially when you know it won't see the light of day again. Our solution? Investing in a rewearable Halloween costume.

The most sustainable items we own are the ones already housed in our wardrobes. So, if you’re up for it, a touch of upcycling can result in a brilliantly unique Halloween costume.
