Lili Reinhart’s plunging top hanging by thin strings became the highlight of her latest promotional look. The actor chose a vintage Emanuel Ungaro two-piece from the house’s early 2000s collections. The archival set featured the label’s signature butterfly and floral print. It also showcased soft pastel watercolor hues across both pieces.

The cropped top featured slim spaghetti straps and a plunging neckline. In addition, ruffled cold-shoulder sleeves created a romantic silhouette fitting for the rom-com’s press tour. The delicate straps made the design appear as though it was held up by only two strings.

Meanwhile, the matching sarong-style midi skirt hugged her figure. Its ruched front draping added fluid movement, while the butterfly motif tied the entire outfit together.

Reinhart completed the vintage ensemble with burgundy heeled sandals. The shoes featured striking metallic 3D butterfly details across the toe straps. As a result, the butterfly print was perfectly echoed throughout the outfit. The coordinated styling gave the archival look a fresh yet playful finish.

Her glam remained soft and effortless. Reinhart wore her blonde hair in loose, smooth waves with a center part. Meanwhile, her makeup focused on radiant skin, rosy pink blush, and a subtle berry-toned lip. Softly defined eyes completed the glamorous appearance without overpowering the pastel palette.

The appearance marked the beginning of promotions for “The Love Hypothesis.” Reinhart looked playful in the photos, striking flirty poses while showing off the rare archival set. Overall, the vintage Emanuel Ungaro look blended nostalgic Y2K fashion with modern elegance, making it a standout moment during the movie’s Brazil press tour.
