UNGD string bikini

Underground Summer Collection

A piece of the artwork. A piece of the season.

The UNGD String Bikini transforms the spirit of the Underground Summer Collection into wearable art. Inspired directly by the signature Underground Summer sunset graphic, this bikini features a zoomed-in section of the original artwork, allowing you to wear a piece of the collection's tropical paradise wherever your adventures take you.

Designed with adjustable string ties at the neck, back, and hips, the UNGD String Bikini offers a customizable fit that moves with you. The classic triangle top creates a timeless beach silhouette, while the side-tie bottoms provide adjustable comfort and a flattering, confidence-boosting look.

Rich sunset tones, tropical flowers, distant mountains, and warm island skies come together to create a design that captures the feeling of chasing the last rays of daylight along a tropical shoreline.
