Water Drift Thong


“Sea levels are rising and if climate change continues, Amsterdam will be completely engulfed by the year 2300.”

135,00 114,75



This colourful embroidered Thong is inspired by the ‘Dutch Drift’ against water. The Dutch are experts in water management and monitor water levels in every river, canal or lake. Our drift against rising sea levels has been a fight to control the waters around us for centuries. The colourful embroidery in this garment is derived from a graph of water levels in the Boezemgemalen (water pump stations) during heavy rain in 2017. The Boezemgemalen pump water out of the lowest areas of the Netherlands. The Water Drift Collection depicts dry feet should not be taken for granted in The Netherlands, as soon the rising sea levels will be uncontrollable.

Every pattern piece in the Water Drift Collection is carefully embroidered separately and aligned on tulle so the graph is not disturbed. The Water Drift High Waist Thong is perfect to complete your lingerie set with the Water Drift Structured Bra or Bralette. The high rise design smoothes your silhouette in the most elegant way. Diagonal lines going from front to back empower your contours. A playful stripe at the back creates a bold look and the shape of the bottom edge is carefully designed to emphasize your curves.

Inspired by the Taskforce Fashion After Flood project.
