Last year we dressed our quadruplets as different farm animals and I was a farmer. We borrowed a HUGE red wagon from some friends, filled it with hay and sat the babies inside as they were not all walking yet. We stole the hearts of many as we walked through the neighborhood with our adorable Pig, Cow, Chicken and Lamb in tow! My costume was a simple white tank, a pair of overalls completed with drawn on freckles & braided pigtails. This year's costumes?! As excited as I am about them, you'll have to wait and see!!!!
Other ideas for multiples include: Lil' Bo Peep and Her Sheep, Bakers and Cupcakes (B/G), M&Ms, Thing1 Thing 2 Thing 3 (a little over used in my opinion), Flower & Bee, Rageddy Ann & Andy, 3 Blind Mice, The 3 Stooges, All Dogs/Cats "A litter", Football Players & Cheerleaders, Alvin & The Chipmunks, Smurfs, All Pumpkins (A Pumpkin Patch)...etc.
I personally love the random coordinating costumes, ones that are not characters. Ketchup & Mustard, Pieces of Fruit or Candy, PB&J, Ham & Cheese, Salt & Pepper, Playing Cards...
