Luis Santiago, a student at University of Wisconsin-Stout's School of Art and Design, is entering his final semester this year, and he already has a popular sunglasses design on the market.

Rainy Days, pictured above, are the sunglasses that he designed in late 2010 for Coco And Breezy, an online supplier of sunglasses, fashion eyewear and accessories.

"Their style is very different, very out there. It’s not a regular sunglass, " says Santiago. When asked about his final design choice he said, "I tried to keep it fairly simple and true to their brand." And it looks like his decision paid off. A few months after he submitted his designs, he was asked to create a 3D model and engineering specifications for production in to China.

By the fall of 2011, his sunglasses had their debut at the New York Fashion Week and were even been featured in Beyoncé's music video, "Party", modeled by none other than Coco and Breezy themselves. Check out the video below and see if you can spot the Rainy Days or any of our party sunglasses:

With the success of Rainy Days, Santiago has now become the lead designer for Coco and Breezy. "I’ve always wanted to design wearable products. Rainy Days has really helped with my portfolio. It’s a pretty big step," he said.
