# Sun-Tanning Satchels The Building Block + Waka Waka Collection Changes When Exposed to the Sun By Meghan Young | Published 2013-03-01 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/building-block-waka-waka References: [refinery29](http://www.refinery29.com/building-block-bags) & [building--block](http://building--block.com/news/72) The Building Block + Waka Waka collection is comprised of purses that react to the sun much like a person does. Not in an emotional way, but in a physical one. Essentially, it [changes color](https://www.trendhunter.com/trends/pangolin) as though it were [sun-tanning at the beach](https://www.trendhunter.com/trends/inflatable-tanning-pool). Each handbag has been made out of time-treated leather, which is what allows this unique reaction to occur. Although that might be enough to set apart the handbags in the Building Block + Waka Waka collection from others, they have been given unique shapes that make them look more like [art pieces than accessories](https://www.trendhunter.com/trends/artycapucines-vii). For instance, one purse sports a squiggly wooden handle while another has geometric blocks embedded in it. The Building Block + Waka Waka collection also has tassels to further customize them. ## Trend Insights (Trend Hunter) - Score: 2.6/10 - Popularity: 47% | Activity: 24% | Freshness: 8% - Audience gender: 10% men, 90% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Fashion](https://www.trendhunter.com/fashion) > [Hip Fashion](https://www.trendhunter.com/hipfashion) ## Key Themes ### What's Driving This Trend - **Color-changing Fashion:** Color-changing accessories and clothing that react to different environmental factors present opportunities for innovative fashion brands. - **Artistic Handbag Design:** Handbags with unique shapes and artistic elements offer potential for disruptive innovation in the fashion and accessories industry. - **Customization in Fashion:** The inclusion of customizable elements like tassels in accessories provides opportunities for personalized fashion experiences. ### Who This Affects Most - **Fashion:** The fashion industry can explore color-changing fashion and artistic handbag designs to captivate customers and stay ahead of the competition. - **Accessories:** The accessories industry has the potential to embrace color-changing accessories and incorporate novel designs to attract consumers seeking unique and personalized products. - **Consumer Goods:** The consumer goods industry can leverage customization trends in fashion to create personalized products that resonate with modern consumers. ## Related on Trend Hunter - [Architecture-Inspired Handbag Capsules](https://www.trendhunter.com/trends/furla-debuts.md) - [Summer-Ready Waxed Leather Accessories](https://www.trendhunter.com/trends/waxed-leather-collection.md) - [Chic Shadow Effect Suitcases](https://www.trendhunter.com/trends/suitcase-of-the-light.md) - [Versatile Warped Handbags](https://www.trendhunter.com/trends/mschf-3.md) - [Avant-Garde Handbag Designs](https://www.trendhunter.com/trends/hanifa.md) - [Sunwear Active Lifestyle Brands](https://www.trendhunter.com/trends/watskin.md) - [Urban Geometric Totes](https://www.trendhunter.com/trends/bao-bao-issey-miyake-1.md) - [Color-Changing Eyewear](https://www.trendhunter.com/trends/rayban-original-wayfarer-change-transitions.md) - [Woven Statement Totes](https://www.trendhunter.com/trends/holst-lee1.md)
