Ya know my first thought was gigantic 5 foot wings like I saw in the costume shop at first. I just couldn't imagine them in the crowded halls or sitting in the dining chairs with arms.
But, yours sound lovely. Perhaps you could post a pic because now I'm interested.
I might just dress as the fairy godmother for formal night.
DS (2.5) wanted these at the Expo....sigh....I say have fun!
Not a good Idea for an adult or any one over the age of 8. Not even for a disney cruise.
If you want to wear them, go ahead, it's your vacation so make the best of it!
Some of the posters who have commented are outright rude, and more than likely they would be the same party poopers that *try* to spoil everyone elses fun on the cruise! You know the type, crabby, complaing, nothing can make them happy, holier than thou, miserable people.
Just ignore them...go and have a great time!
