Color palette for an off-shoulder boatneck dress: blue and purple

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 P0690 is metadata only and must not appear in the image.
THREE REAL REFERENCES: Image 1 is Marilyn Monroe identity reference (MONROE_CLEANWHITE); preserve her recognizable face, facial proportions, age, natural expression, blonde hairstyle and natural skin. Image 3 is the EXISTING exact garment-and-shoe reference (F039); dress her in ALL those garments and its one complete pair of shoes. Image 2 is the authoritative four-band palette, source order #F29AAE, #C47BE4, #7132CA, #301CA0.
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: Boatneck off-shoulder dress with flared skirt. 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 cotton boatneck dress, short sleeves covering upper arms, fitted waist, midi flared skirt): #301CA0 (clothing_primary); belt (original narrow self-fabric belt of the main garment, laid flat at its original waist position, without added accessories): #C47BE4 (accent); shoes (one pair of low-wedge sandals, left and right shoes completely and independently displayed, uppers, sole edges, and all laces or buckles clearly visible): #7132CA (secondary). Whole main garment must visibly carry #301CA0, with realistic highlights and shadows. Environment main supporting color #F29AAE, small supporting surfaces/details #7132CA and #C47BE4. 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 summer, chosen as an artistic suitability recommendation. Scene: a restrained sunlit summer courtyard or terrace, warm bright daylight, airy atmosphere. Pose: natural relaxed standing with one foot slightly forward, arms relaxed. 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.
SKIN PROTECTION: Skin is excluded from all palette recoloring. Keep the face, ears, neck, exposed upper chest, arms, hands and legs in coordinated natural skin tones with believable light and shadow. Do not allow garment or environment colors to tint skin cyan, green, gray, blue or an unnatural color. Preserve real complexion variation; do not flat-fill the body with a single paint color. Check especially the neck below the jaw and the exposed skin inside collars.
Verified reference appearance corrections (preserve the actual source design and the existing region HEX assignment): belt: narrow leather buckle belt from original reference, retain buckle shape and original waist position, recolor with specified accent color
Stand relaxed with feet SIDE BY SIDE about 20 cm apart, no crossing or overlap. Both woven-rope wedge sandals complete with crossed forefoot straps and ankle buckles, preserve reference modest wedge height. Dress retains off-shoulder neckline, short puff sleeves and full midi skirt, narrow buckle belt. Skin of neck shoulders chest arms and legs must stay natural, absolutely no purple/blue color spill.
