Aristocrat Sassa de Osma has showcased an early autumn transitional outfit featuring a red alpine vest during a vacation in St. Moritz, Switzerland.
The garment from alpine fashion brand La Forestia connects with traditional mountain style while offering an adaptable option for late August that can easily transition to city streets such as Madrid in September.
Sassa de Osma, also known as Princess Alessandra of Hanover, is a Peruvian aristocrat, model, and fashion entrepreneur based in Spain. St. Moritz, situated in the Swiss Alps, is renowned as a high-altitude resort destination where cooler late August temperatures prompt an early shift toward layered autumn clothing.
As temperatures begin to drop in the mountains, long-sleeved shirts and waistcoats return to regular wear over summer blouses and dresses. The aristocrat selected a mountain-inspired look for a day outdoors while avoiding an overly traditional folklore costume.
Details of the La Forestia alpine vest
The red vest was created by La Forestia, an alpine fashion brand founded by Cleo Oettingen-Spielberg and Farina Maria Pavel. The label focuses on reinterpreting traditional mountain clothing codes into contemporary designs.
Priced at 450 euros, the piece features an intense red shade, contrasting trim along the edges, and a front button closure. In St. Moritz, Sassa de Osma wore the vest over a white blouse with structured, voluminous sleeves, allowing the vest to define her silhouette and provide a bold pop of colour.
To complete the ensemble, she paired the waistcoat with classic blue denim and matching ankle boots. Combining the traditional garment with modern denim and boots removes its purely rustic feel, making it suitable for everyday urban wear.
Transitional style for September wardrobes
The choice highlights a practical transition strategy for September fashion. Wearing a vest allows light summer shirts and blouses to stay in rotation as weather cools without requiring a heavy winter jacket.
The red vest is part of a broader late-summer aesthetic that the entrepreneur displayed throughout her stay in Switzerland. Her outfits in St. Moritz have consistently incorporated knitwear, warm color palettes, and handcrafted accessories tailored to the mountain setting.
Rather than making an abrupt seasonal shift, her wardrobe demonstrates a gradual transition. The approach combines summer staples like jeans and light tops with autumn elements such as knitwear, suede pieces, and earth tones as footwear transitions from sandals to loafers and cardigans are draped over shoulders.
