EX's first collection is themed around natural elements, including mountains, sea, trees, flowers, and animal prints. To maintain a unified style, the back designs are all inspired by these elements and integrated into visually appealing and unique images.

To make the wearer stand out without being overly flamboyant,
a strong contrast is deliberately created between a simple front and an eye-catching back, adding a playful touch and making the wearer more individualistic and recognizable compared to typical sportswear.
