Phillipa String Bikini Bottoms

Product Insights & Style Tips

The Phillipa string bikini bottoms by SIR bring a sun-drenched retro mood to the water. They sit low at the waist with a high cut through the leg, shaping a leg-lengthening silhouette that feels playful and confident. The vintage-inspired stamp print offers graphic contrast, while the fabric—76 percent nylon and 24 percent elastane—delivers soft stretch and recovery. The lining uses 74 percent nylon and 26 percent elastane for a smooth hand and secure coverage.

Adjustable self-tie sides let you dial in the hip fit as you move from lounging to a dip. The low-rise sits softly and the high-cut leg skim the body without pinching, while the stretch fabric moves with you through beach days and poolside moments. The lined interior keeps things tidy under a sheer cover-up or when pairing with a different top, and the compact silhouette layers cleanly beneath resort-ready caftans. Imported. Hand wash.

SIR leans into a signature mix of vintage flair and contemporary cut, and Phillipa bottoms fit that code with a statement print that feels fresh. Pair with the matching top for a coordinated set, or mix with a crisp cover-up for a day-to-night beach look that travels as well as you do.
