(In case you missed Part One, you can find it here.) Everyone brought out the big Halloween guns this weekend, from Katy Perry to Rihanna to, as always, Heidi Klum. As usual, half the time I can’t figure out who people are dressed as, so let’s gather around as a village and try to figure some of these out. Hope your Halloween was spectacular.
