Create a detailed full-body illustration of a noble Celtic-inspired fantasy dress displayed on a realistic female mannequin with a natural hourglass figure. The gown is made in a deep dark teal color (Hex #014d4e) with subtle variations in tone and luxurious matte fabric. The dress features long fitted sleeves and an elegant rounded chest cutout integrated harmoniously into the design, serving as a refined decorative element rather than a revealing feature. The silhouette reflects the fashion of the late 15th century with fantasy influences: a fitted bodice, gracefully flowing floor-length skirt, and slightly extended train. Fine Celtic embroidery in muted silver and antique gold decorates the cuffs, collar, waist, and hem without overwhelming the design. Delicate knotwork, stylized oak leaves, and subtle wolf motifs are woven into the embroidery as a tribute to Irish heritage. The neckline is modest and elegant, complemented by a high standing collar and tasteful trim. The waist is accentuated by an embroidered belt with bronze Celtic ornaments. The fabrics appear rich yet practical, combining fine wool, soft linen, and lightweight velvet suitable for a respected noblewoman. The overall aesthetic should convey quiet nobility, wisdom, and dignity rather than extravagance. The design should feel appropriate for an Irish-Celtic noblewoman and mayor during the late medieval period, balancing historical authenticity with refined fantasy.
