With only a few weeks left until Halloween (and a son who’s extremely excited about it!), I’ve started to think about what I’ll wear as a costume. Because shopping for an entirely new ensemble takes time and can end up being pricey, I always start my brainstorm by looking in my closet, asking myself: Are there any existing pieces I can easily rework into a Halloween costume?

Thanks to my fall wardrobe this year, there are several options I can quickly transform into fun, classy looks for Halloween. Based on outfits I regularly wear in real life, they’re perfect for going straight from the office or running errands to a Halloween event. Just pack a few costume add-ons in your bag for the day, and you’re ready for celebration mode!

What You'll Need:

  • Chambray shirt
  • high-waist jeans
  • red bandana

  • white blouse
  • black tights and boots
