She is wearing an elegant, princess-like white mini dress with a see-through lace bodice adorned with pearls, flower embroidery, and small ribbons, paired with a voluminous multi-layered tulle skirt. On her feet, she wears platform high heels with crossing silver glitter straps (transparent platform soles, metallic silver stiletto heels, and ankle straps), and she wears a silver tiara. She is singing into a black microphone with a joyful expression, making a perfect heart shape with her other hand near her face. Around her, other young women wearing white T-shirts and black layered frilled skirts with glossy black short platform boots are dancing and clapping.
