Navy Sheath Dress with Illusion Sleeves, Lucy

The Lucy Navy Illusion Sleeve Sheath Dress is a sculpted crepe knee-length sheath in midnight navy, finished with tailored illusion mesh sleeves and a jeweled clasp at the collar. It is built for women whose calendar moves from boardroom hours into evening reception inside a single day, with the sheath silhouette reading as authority and the illusion sleeves softening the line for evening.

Fabric
97% structured technical crepe with 3% elastane, sourced from a European mill. The crepe weight gives the sheath silhouette its sculpted line through the body, and the elastane content provides shape recovery across long seated wear. The illusion mesh sleeves are tailored to the arm, designed to frame the shoulder line with a soft veil of light rather than reading as transparent. The jeweled clasp at the collar is a single focal point, calibrated to read as restrained rather than ornamental. Designed and crafted in Europe as part of Luna Fashion House. Featured at OC Fashion Week 2026, Catalina Island runway.

Fit
Slightly generous in fit, with a sculpted silhouette through the bodice, natural waist, and hip. The crepe holds line through a full day without compressing. The illusion sleeves fit close to the arm and end at the wrist. The dress finishes at the knee, with refined hip pocket flaps as a tailoring detail. Between sizes, choose the smaller for closer sculpted line or the larger for additional ease through the body. See the Luna sizing guide for measurement specifications. Model is 5 foot 9 inches wearing size 2. The length is 39” from the back of the neck to the hem on a size 2.

Styling
For mother of the bride at a black-tie wedding, pair with satin heels and the Jody Lace Clutch Bag in Black for tonal grounding against the navy.
For executive presentations and board meetings, the Agatha Pearl Detail Blazer in Ivory layers cleanly over the sheath for daytime authority.
For charity gala arrivals, the Selina Wool Cape in Black drapes over the illusion sleeves for sculptural arrival.
For cocktail evenings and foundation dinners, the Julia Evening Clutch Bag in Yellow adds a single color note against the navy.
For winter formal ceremonies, the Clara Wool Trench Coat in Navy Blue sits in a tonal navy family for arrival photographs.
Silver and platinum read cleaner against navy than warm gold; hold one metal across all hardware including the jeweled collar finish.

Care
Machine washable on a gentle cycle. Air dry. Steam or iron on low if needed. Spot clean small marks with cold water. Do not bleach. Store on a broad padded hanger to preserve the sculpted shoulder line.

The coat over it

The Lucy sheath ends at the knee. Red over navy works for the office, and the Red Wool Coat with Faux-Fur Collar, Selina reaches the knee or a little below, so the dress stays under the coat. It costs $825. The Navy Wool Trench Coat, Clara ($910) keeps the outfit all navy and runs well down the calf.
