S1·E19 The Makeover

Vanity convinces Tailor Smurf to make a new outfit for the Smurfs. After Jokey gets a hold of it, he and a few other Smurfs greatly change it up, which causes Vanity to accuse Tailor of being a bad Tailor, which causes them to fight in an all-out war. Other Smurfs begin rooting for one or the other and abandon their clothes until a new outfit is made.
