🕷️Wednesday Addams Party
Since OG teen goth girl, first appeared in 1944, never has she grabbed more attention than now.
While we love us some Christina Ricci and others who have played the iconic character, Jenna Ortega is killing it.
Wednesday, the Netflix series, exploded on the scene last fall, and a new season just dropped, so I think a Wednesday Addams party makes for a hit with teens and tweens.
" I should have known you were behind this. What part of "no party under the penalty of death" do you not understand?"
