What to know about Oseree
Metallic lurex is the signature
The Lumière line's shimmering lurex knit runs across bikinis, maillots and kaftans, joined by sequins, feather trims and ring hardware — poolside, not discreet.
Menswear is the newest chapter
Founded in 2015 as a women's swim and resortwear label, Oseree only added menswear for spring 2025, so the men's offer sits inside a swim-first house.
Italian swim production, resort pricing
Pieces are made in Riccione on Italy's Adriatic coast, and the brand's mid-high pricing reflects that plus a swim-week and celebrity-worn profile.
