Act as a professional logo designer with 10 years of experience in sustainable branding. Create a minimalist yet impactful logo for an eco-friendly clothing line called [BRAND NAME]. The logo should incorporate organic shapes, earthy tones like [PRIMARY COLOR] and [SECONDARY COLOR], and subtle nature-inspired elements such as [LEAF/WAVE/TREE]. Ensure the design reflects sustainability, elegance, and modernity, suitable for both digital and print use. Avoid clichés and focus on clean, scalable vector art. The final deliverable should include a primary logo, a monochrome version, and a favicon adaptation.
