While Halloween may be our favorite holiday, our celebrations become a bit limited as we age. Heading to work in a head-to-toe costume may not be considered kosher by your boss and knocking on your neighbor's door to trick-or-treat past a certain age is...most definitely not okay. We've already started indulging in some candy and have planned costumes for our nighttime plans, but to get in the spirit during the day? Decorating our digits! Go to town with these at-home manicures or bring them to inspire your favorite nail salon. Either way, these monster manicures are the perfect and subtle way to express our love for this holiday!
