Day Birger Portia Swimmy Bikini in Black

Swim, refined.

The Day Birger et Mikkelsen Portia Swimmy Bikini in Black is a clean, minimal take on modern swimwear. Designed in a timeless black tone, it delivers that effortless, confident feel — understated, but always considered.

With a flattering, streamlined fit and soft stretch, it’s made to move with you while keeping its shape. Simple lines, no excess — just a polished, elevated approach to swim.

Less, but better.

Why we love it:

• Soft, stretchy fabric for a comfortable fit
• Clean, minimal design with a flattering silhouette
• Classic black for a timeless, versatile look
• Holds its shape wear after wear
• A refined take on everyday swimwear

Style notes:
Pair with an oversized shirt or lightweight cape for an effortless beach-to-bar look. Keep it tonal with black or soften with neutrals.
