String Bikini: Heart of Stone Collection in Ollie

Make a dreamy statement with the Ollie String Bikini from Mod Millennial Designs. Part of the Heart of Stone Design Collection, this bikini features a fluid marble-inspired pattern dominated by soft blush and bubblegum pink with swirling aqua-turquoise, pale blue, and white accents. The actual product photos show an airy watercolor-like stone pattern flowing across the triangle top and tie-side bottoms, creating a playful pastel look that blends marblecore, Y2K, feminine, and artistic aesthetics.

Made from soft, stretchy recycled polyester and elastane fabric, this women’s string bikini features UPF 50+ sun protection and comfortable double-layered construction. The bikini top includes removable padding, while adjustable ties allow the set to be customized and styled in multiple ways. With its classic triangle silhouette and tie-side bikini bottom, Ollie is designed for beach vacations, pool days, resort escapes, and colorful summer styling.
