During Buffy the Musical Buffy goes to the Magic Box, and she learns that Dawn has been kidnapped by a musical demon. Giles says she has to go alone. Well we see Buffy wearing a white shirt. She leaves and puts on a black jacket, but you can still see the shirt. So she makes her way to the Bronze singing..."I touch the fire and it freezes me...I look into and its black....etc." Then Buffy breaks down the door to the Bronze and she talks to the demon. Then while she removes her black jacket and begins to sing "Life's a show and we all play are parts...etc." we see she is wearing a red shirt now. Apparently Dawn's life could wait for a costume change.
