OIA is a Swedish beachwear brand, founded by three women in their twenties to introduce a fresh, Mediterranean-inspired take on bikinis and to challenge the stigma surrounding traditional sizing.

OIA was born from our shared love for the Mediterranean’s timeless charm—its azure waters, golden sands, and vibrant coastal culture. We set out to create more than just swimwear; our vision was to build a brand that celebrates individuality, natural beauty, and the confidence to express yourself freely. Inspired by the Mediterranean lifestyle, our designs are made to capture its effortless elegance and bold spirit.

Recognizing the stigma with outdated sizing systems, we developed a new, more inclusive approach. Our sizing system is inspired by the Mediterranean’s diverse natural elements, where each size is represented by symbols of this rich environment, made to give you a more liberating view on our own body.

Whether you're exploring hidden coves, lounging on a secluded beach, or strolling through coastal towns, our swimwear is made to stand out and celebrate your individuality.

We can’t wait to share the joy of OIA with you and make your beach days even brighter.

Love,
Team OIA
