Ep 3. Blacklight or Daylight?

In Project Runway season 15 episode 3, titled "Blacklight or Daylight?", the remaining designers are challenged to create a look that can transition from daylight to blacklight. The episode kicks off with some behind-the-scenes drama, as the designers react to the previous week's elimination and discuss their strategies for the upcoming challenge.

The designers are presented with a variety of fabrics, including neon hues and reflective materials, to create their looks. They have just one day to complete their designs, which must reflect their personal styles while also incorporating the blacklight component.

As they work, the designers face a number of obstacles. Some struggle with the concept of transitional design, while others struggle to balance their personal style with the blacklight element. Several designers also face technical difficulties, such as dealing with fabrics that do not react well to the blacklight.

In the midst of the chaos, mentor Tim Gunn visits the workroom to offer advice and critiques. He encourages the designers to take risks and push their boundaries, but also reminds them to stay true to their personal aesthetic.

As the clock ticks down, the designers scramble to finish their looks. Some are able to complete their designs with time to spare, while others are forced to rush through the final touches. Once the time is up, the designers present their creations on the runway.

The judges, including designer Zac Posen and supermodel Heidi Klum, critique each look in detail. They consider the designers' use of color and texture, as well as the effectiveness of the blacklight component. Some designs are praised for their creativity and innovation, while others are criticized for being too safe or lacking in execution.

In the end, one designer is declared the winner, earning immunity for the next challenge. Another designer is deemed the loser, and is sent home. The episode ends with a teaser for the following episode, leaving viewers eager to see what challenges the remaining designers will face next.
