[Purpose]
Korean fashion brand seasonal lookbook poster, editorial campaign layout for social media and print.
Premium designer-brand lookbook poster with cinematic hero fashion photography, clear collection information blocks, real event-style details, and polished campaign graphics for a seasonal collection launch.

[Composition]
- Center the main model hero in a full-body or half-body vertical composition, occupying about 60% of the frame, with the upper area used for branding and the lower area used for collection/event information.
- Keep {브랜드명} as the primary brand mark near the top, with {시즌컬렉션} as the headline and {컬렉션메시지} as the supporting campaign statement.
- Place {키룩컨셉} as the visual styling direction for the outfit, making the garment silhouette, fabric texture, seams, accessories, footwear, and styling details clearly readable.
- Build a realistic fashion poster grid: hero fashion image, collection title, look number label, launch date, pop-up/event information, ticket or reservation note, sponsor/partner strip, website, and hashtag line.
- Background should feel like a contemporary fashion studio or urban editorial set: matte off-white wall, charcoal floor, muted green painted panel, soft concrete texture, fabric backdrop, or subtle set pieces such as a chrome stool, garment rack edge, floor tape marks, acrylic block, or paper sweep.
- Add refined poster details that naturally appear in a seasonal collection campaign: thin divider rules, small vertical labels, lookbook code, price/reservation note, tiny barcode-like catalog mark, and subtle decorative geometric accents in the signature color palette.

[3. CORE STRUCTURE]
1. Top branding zone (10–15%): place {브랜드명} as a designer wordmark, centered or slightly left-aligned, with {시즌컬렉션} directly beneath it as the main campaign title. Add a small date label reading {룩북날짜} and a vertical spine-style credit such as “LOOKBOOK POSTER / {브랜드명} / SEOUL”.
2. Hero fashion zone (middle 55–65%): show a Korean model in {키룩컨셉}, either full-body or half-body, with editorial posture, strong garment silhouette, realistic clothing folds, visible signature accessories, and natural interaction with the studio or urban set.
3. Message and look label zone: place {컬렉션메시지} in a compact caption block, then add a small label such as “LOOK {룩번호} / EDITORIAL DROP” near the model or side margin.
4. Information box zone (lower 15–20%): add a structured campaign info panel containing {발매구매}, {행사시간}, {행사장소}, {티켓정보}, and {웹사이트}, aligned to the editorial grid and separated by thin rules.
5. Sponsor and decorative zone: include a small partner/sponsor area reading {후원표기}, a hashtag line {해시태그}, a tiny barcode-like catalog graphic, and abstract graphic accents such as coral corner tabs, green vertical bars, cropped circles, or thin diagonal fashion-layout marks.

[4. STYLE RULES]
- Typography: Pretendard or Noto Sans KR for the main Korean text, weight 500–700 for headings and 300–400 for body copy; use 34–52px for the title, 16–22px for subcopy, and 12–14px for small info labels.
- Color palette: charcoal #111111, off-white #F4F1EA, deep green #1F4D3A, coral accent #FF6B5A, muted gray #8A8F98; allow {컨셉톤} to guide the accent balance.
- Border/shadow: thin 1px divider lines in #CFCBC2, soft drop shadow 0px 8px 24px 12% opacity on the hero cutout or information box, with realistic printed-poster depth and subtle paper grain.
- Layout texture: allow visible paper fibers, studio floor shadows, fabric weave, garment texture, small editorial labels, date stamps, and campaign catalog marks so the poster feels produced and physically plausible.

[5. VISUAL STYLE]
- Camera / lens: editorial fashion photo shot on a medium-format camera look, 85mm portrait lens at f/2.8 for half-body or 50mm equivalent for full-body, clean sharp garment detail and natural body proportions.
- Lighting: soft studio key light from upper-left at 45°, gentle fill from right, subtle rim light to separate the model from the background, with controlled contrast for a high-end lookbook finish.
- Color grade: muted monochrome base with signature black + green + coral accents, slightly warm neutral skin tones, and refined contrast inspired by modern fashion campaign grading.

[6. MOOD]
Korean designer-brand lookbook editorial — somewhere between W Korea fashion spread and Acne Studios campaign precision, with a premium runway-poster sensibility, Seoul pop-up launch energy, and polished seasonal campaign realism.

[7. CRITICAL]
- Korean text accuracy: the following strings must appear exactly as written in the rendered image:
  - {브랜드명}
  - {시즌컬렉션}
  - {키룩컨셉}
  - {컬렉션메시지}
  - {발매구매}
  - {룩북날짜}
  - {행사시간}
  - {행사장소}
  - {티켓정보}
  - {후원표기}
  - {웹사이트}
  - {해시태그}
  - {룩번호}
- The model must look like a Korean 20s fashion model with anatomically correct proportions, clean clothing folds, realistic accessory placement, and believable fashion-poster posing.
- Keep the text hierarchy clear: brand mark, season title, campaign message, look label, launch/event details, ticket/reservation information, sponsor strip, then website/hashtag microcopy.
- Render the lower info panel like a real printed launch poster, including small dividers, catalog code styling, a barcode-like mark, and readable Korean typography.

[8. 🚫 PROHIBITED]
- Fake official seals / certifications
- Broken Korean characters
- Celebrity composites or recognizable public-figure likenesses
