I am acquiring costume paraphernalia for Halloween parties that haven’t even been conceived yet. If there is a costume contest, I will be there with bells (and wigs and masks and tutus) on. You’re better than that. I once thrifted a hand-sewn ET costume clearly made with love by a janky seamstress, and it remains a Halloween costume highlight. Look up old Halloween costume photos, scour eBay for retro plastic masks or do your hair and makeup reminiscent of a bygone decade.
