For the special appearance, Heidi Klum wore a black long-sleeve stretch crepe gown from Christian Siriano’s Spring 2026 Ready-to-Wear collection. The Black Long Sleeve Gown with Gold Lace-Up, priced at around $5,600, featured an eye-catching gold lamé lace-up design running down the center. Matching lace-up detailing also extended along both sleeves, creating a bold, sculptural effect.

The plunging front of the gown drew attention with its open lace-up construction. As a result, it offered a glimpse of Klum’s coordinating black underwear beneath the intricate gold detailing. Meanwhile, the floor-length silhouette flowed into a subtle train, balancing the daring neckline with elegant proportions.

Klum kept her accessories minimal. She completed the look with a few statement rings that added sparkle without competing with the gown. Moreover, her long blonde hair was styled in soft, voluminous waves. A center part framed her face, enhancing the glamorous finish.

Her makeup complemented the dramatic ensemble. She wore a glowing, sun-kissed complexion with softly contoured cheekbones and peach-toned blush. In addition, her smoky eye makeup featured dark eyeliner and generous mascara. A glossy nude lip finished the polished beauty look.

The 53-year-old model confidently posed against a shimmering gold backdrop. The metallic setting echoed the gown’s striking lace-up accents. Consequently, the entire look felt cohesive and runway-ready.

Christian Siriano’s design blended sophistication with bold detailing. The structured stretch crepe silhouette highlighted Klum’s figure, while the gold lace-up panels gave the gown a modern edge. Paired with understated jewelry and glamorous beauty, the statement dress perfectly matched the celebratory mood as “Project Runway” Season 22 heads toward its highly anticipated finale.
