Take a pink or white sweat suit and get pink and white balloons and blow them up and pin them to your sweat suit.
Sprinkle glitter all over you then put on a shower cap and get a bath sponge!
Thanks to Jazzmin for this very fun idea!
Another Idea
For the bubble bath, get a large toy tub and cut the bottom out, then add straps to the sides and wear it as a tub for your bubble bath costume.
I borrowed this idea from my neighbor who dressed up as bubble bath one year.
She looked really cute. She even added an empty box of Mr. Bubble to it!!!!
Thanks to Susan for this addition!
