Reilly's And Camille's Costumes....

Let's just say that they're not exactly pup-proved.

(You thought that "Momma"/"Auntie Nicole" would reveal what the Halloween costumes are, didn't you? Not without making a Halloween card! Trick for treat, and the treat will be a Halloween card with Reilly and Camille in their costumes!

(Anyway...)

1. Reilly and Camille hate dressing up in general.
2. "Mimi"/"Auntie Michelle" (despite that she thinks that the costumes are cute) certainly did not help "Auntie Nicole/"Momma" get Camille and Reilly to get their costumes on them as much as she could have helped her.
3. The costume for Reilly was bigger than expected, despite that it's size adjustable.
4. Probably due in part to flaring-up-of-late OCD/Anxiety, "Momma" likely left the costume a little too loose since she doesn't want to choke Reilly. 

PS "Trick for treat" definitely encompasses Reilly's allowing "Momma" to put on the costume in exchange for getting a treat.
