Retrato grupal de Blue Couture

A luxurious studio fashion portrait of {argument name="group size" default="four"} elegant young women posed closely together in a dramatic royal-blue fantasy setting, all wearing coordinated deep sapphire and midnight-navy couture evening gowns with glittering beadwork, floral appliqué, sequins, lace sleeves, sheer mesh details, and voluminous layered skirts. The scene is monochromatic blue with a cool, moody, high-end editorial color grade. Arrange the women in a tight triangular composition: two standing or elevated in the back and two seated in front on draped fabric, with varied graceful poses, one woman raising an arm above her head, one leaning slightly, one seated upright, and one resting her chin on her hand. Their dresses should each be distinct but harmonized, featuring ornate crystal embellishments, embroidered flowers, and fitted bodices. Add matching sapphire jewelry including dangling earrings, gemstone necklaces, and floral hair accessories. Use long flowing hair in mixed dark black and soft light brown tones, styled smooth and glamorous. Surround them with opulent set dressing: 2 classical urn vases filled with blue roses, 1 fluted stone column in the background, heavy shimmering velvet curtains, and abundant draped satin fabric pooling around them. Lighting should be soft and diffused with subtle highlights on satin and jewels, creating a regal, mysterious, romantic atmosphere. Shoot as a vertical fashion editorial portrait, waist-up to full seated composition, highly detailed fabric textures, polished luxury beauty campaign aesthetic, no visible text.
