Your copy should reflect the tone, world, and aesthetics of the brand\u2014not just the product benefits.\nHere\u2019s what you need to know to build a winning ad:\n\ud83d\udccc Brand/Product Info\nWebsite/Product collection: {{ $json['Product Name'] }}\nDescription: {{ $json['Product Page Link'] }}\nKey differentiators (if any): {{ $json['USP - 1 liner'] }}. Also see attached for additional information\nTarget audience: {{ $json['Target Audience'] }}\nPain Points: {{ $json['Pain Points'] }}\nReference Ads:\n Also included are sample ads that previously worked for the brand or category. Use them to understand the visual tone, caption style, and level of copy aggression. (Avoid being too pushy. Fashion = allure, not pressure.) - {{ $json['\\'Proven Winners\\' Ad Samples'] }}\nAnother set of ad copies from competitors for additional data - {{ $json['Ad Copies from Competitors'] }}\n\nCustomer Review - {{ $json['Customer Review (optional)'] }}\n\n\u26a0\ufe0f Key Guidelines to Follow:\nKeep it cool \u2013 Never sound desperate for a sale. Cool > Clear.\nLess is more \u2013 One-liner captions often perform best. Silence is power.\nBrand comes first \u2013 The tone should sound like it\u2019s from the brand\u2019s own Instagram, not a sales rep.\nDirect-response formats (problem \u2192 solution) rarely work in fashion.\nVisuals do the heavy lifting \u2013 Sometimes, the best copy is no copy. Keep that in mind.\nStay aligned with the fashion ecosystem \u2013 If it wouldn\u2019t be seen on a Dior, Moshi, or Reformation ad, don\u2019t say it here.\n\u2705 Deliverables:\n3\u20135 ad copy variations (60 characters to 90 words max)\nUse the format: Hook (optional) + Vibe Copy (brand voice) + Optional Tagline (if needed)\nKeep it minimal, editorial, and always in-brand.\n\n{{ $json['Attach Research Brief and other references'] }}\n"
