I found some pictures on Una Di Noi of Roxy in her Tutti-Fruiti outfit, and thought it was too awesome not to share on here! Really, I didn't know Roxy had a Tutti-Fruiti outfit. When all the girls were dressed up like this, Roxy was always in her cute waitress-y outfit, so I don't think this was ever shown in the show.
All the other girls have a fruit theme (click here to see other outfits). Bloom's is oranges, Stella's is pineapple, Layla's is watermelon, Flora's is strawberry, Musa's is cherry, and Tecna's is grapes. Roxy's is a little harder to figure out. What do you think it is?
