"Create a calligraphic, elegant logo for a premium yoga and pilates boutique studio named 'Golden Apple.' The design should feature a stylized, flowing apple icon that symbolizes luxury, vitality and balance. Incorporate refined, calligraphic lines and simplicity in the apple icon and studio name lettering. Use a sophisticated color palette of white and gold to convey tranquility and sophistication. The calligraphic style should feel both modern and timeless, evoking a sense of awe and high-end branding. The logo should appeal to a discerning clientele seeking a premium yoga and pilates experience and elevate your studio's signage, marketing materials and merchandise. Aim for a minimalistic yet elegant design that stands out."
