Use case: stylized-concept. Asset: exploratory couture millinery design sketch sheet C, DOUBLE EAVE, for a development diary, requiring a milliner's prototype, not a verified construction plan. White paper, delicate graphite and precise brown ink with restrained ivory silk and brown fabric-binding watercolor washes. Landscape sheet with large three-quarter view, smaller consistent front and side views, and small cutaway inside view showing oval head opening, grosgrain inner band and lightweight brim support concept. Abstract head contours for wearable scale, no photographic person. SAME design in every view. Original photo is architectural inspiration only. Reduce the water tower to three legible cues: octagonal flared upper volume, projecting roof-like edges, and brown diagonal accents over ivory. Design a bold but lightweight COUTURE HAT from ivory silk-covered buckram with brown fabric bindings. TWO LOW LEVELS ONLY: low octagonal lower crown with broad thin projecting octagonal eave; a compact upper crown with its own smaller thin eave. Finish with a very shallow pitched fabric top, no high point or finial. Both levels should form a unified wearable fashion silhouette; combined height reasonable relative to head, far smaller and less literal than a model tower. Brown fabric bindings on eave edges, a few broad diagonal stitched textile lines over lower ivory crown. Gently flared facets, visible cloth grain and seam softness. Eaves thin and light rather than thick carved architecture. Inside detail suggests crown-to-headband attachment and brim edge reinforcement, without claiming engineered dimensions. NO miniature windows, no miniature timber building framework, no tiny columns, no ornaments, no third level, no spire, no finial, no model tower on head, no photoreal fashion photo. A dramatic textile millinery proposition. Sparse exact text ONLY: large letter "C" at upper left and numbered callouts "1", "2", "3", "4". No other text, no measurements, no claims of tested pattern, no logos or watermark. Airy editorial sketchbook composition with separated clear views and whitespace.
