Guests who attended Julianna Bass‘ show at New York Fashion Week on Saturday would be forgiven if they didn’t notice tech on the runway. That’s because the womenswear designer known for her elegant yet powerful silhouettes took a subtle approach to integrating a colour-changing fabric into her Spring Summer 2018 show. Among the presentation of flocked tulle, fluid sheers, and bold piping, two models walked the runway in colour-changing garments. The first was a white, off-the-shoulder dress with structured pleats that changed colour as it made its way down the catwalk. The second was a tulle gown with a tiered ruffle sleeve with similar pleating.
