Color palette for a chunky-knit maxi dress: blue

Reference order: image 1 is the portrait reference, image 2 is the palette, and image 3 is the clothing and footwear reference.

Use case: identity-preserve, three-reference virtual outfit try-on and color-palette compositing.
Create ONE NEW realistic full-body fashion portrait, exact intended output 1024 x 1536 pixels, portrait 2:3. Production ID P0704 is metadata only and must not appear in the image.
THREE REAL REFERENCES: Image 1 is Marilyn Monroe identity reference (M04_BUS_STOP_AI); preserve her recognizable face, facial proportions, age, natural expression, blonde hairstyle and natural skin. Image 3 is the EXISTING exact garment-and-shoe reference (F098); dress her in ALL those garments and its one complete pair of shoes. Image 2 is the authoritative four-band palette, source order #1A2C5B, #3E4E88, #7971EA, #B8DFF0.
Do not keep the original outfit or background from Image 1. This is a newly imagined full-body fashion composition, not a restoration or recreation of the historic photo. Keep source files untouched. Preserve the identity, not source framing. For a bust or seated identity reference, construct a believable proportional full standing figure. Do not copy source photo captions, watermarks, signatures or image borders into this NEW composition. Do not copy identity-source hat, gloves, jewelry or other costume accessories unless the garment reference includes them.
Outfit: Belted chunky knit maxi dress. Preserve the actual design shown in Image 3: exact garment count, style, neckline, sleeve length, coat/skirt/trouser lengths, collar, cuffs, closures, waistband, pleats, existing pattern geometry, fabric texture, footwear shape, toe, straps, heel and sole. Adapt these existing items naturally onto the body, not flat-lay. No replacement designs or extra accessories. Opaque tasteful clothing.
Apply region colors as follows: dress (opaque chunky-knit turtleneck long-sleeve dress, long column silhouette, ribbed cuffs and hem): #7971EA (clothing_primary); belt (original narrow self-fabric belt of the main garment, laid flat at its original waist position, without added accessories): #3E4E88 (accent); shoes (one pair of square-toe low-heel ankle boots, left and right shoes completely and independently displayed, uppers, sole edges, and all laces or buckles clearly visible): #1A2C5B (secondary). Whole main garment must visibly carry #7971EA, with realistic highlights and shadows. Environment main supporting color #B8DFF0, small supporting surfaces/details #1A2C5B and #3E4E88. Clothes are visually primary; environment secondary. Palette colors guide material colors, not every pixel. Keep natural skin, blonde hair, eyes and neutral physical light/shadow; no global color cast.
Season is winter, chosen as an artistic suitability recommendation. Scene: a restrained winter stone courtyard, subtle snow at distant edges, crisp cool natural daylight. Pose: relaxed three-quarter standing pose with both feet clearly visible. Eye-level fashion photography, naturally graceful and anatomically plausible. Entire head/hair and BOTH full shoes visible with breathing room. Face and important garment detail sharp, backdrop restrained and slightly defocused. No dramatic skirt lifting.
Output one cohesive photoreal human wearing the entire outfit. NO flat lay, mannequin, product board, collage, split screen, extra people, duplicate limbs or duplicate garments. NO written text, letters, numbers, logos, watermarks, captions, color swatches, color card, HEX labels, footer or border. Do not draw the input palette card.
