Next up: the Juno couple.
For this one we used clothes we had on hand and bought name tags and sweatbands for hubby.
Here's a list of our other contenders:
Housewife and Milkman
Santa Clause and elf/reindeer
Bun-in-the-oven and Baker
Squasher and Zombie (from plants vs. zombies the game)
Woman in labor and Super-Dad (Hubby would wear a tool belt with baby supplies)
