One-piece swimsuit made of knitted fabric with a motif of holiday palm trees, perfect for use both on the beach and in the pool. The cut of the swimsuit combines functionality and elegance. The swimsuit has a sewn-in bra with soft underwire cups and adjustable, non-removable straps. The width and type of straps match the size of the costume. Insertions of black material on the sides optically slenderize and model the silhouette. The back of the costume is fastened with a buckle.
