Sierra moves with a confident swagger that makes her seem larger than she is, tinged with a predatory grace that gives the impression that she knows perfectly well how to utilize her body as a weapon, not hampered in the slightest by her lack of raw strength or size. The product of a mixed heritage, a little hair dye and the right clothes can turn her into a natural chameleon, easily able to take advantage of the average Inner Sphere denizen's inability to tell various flavors of Asian bloodlines apart in order to pass for a native from any of a plethora of non-Republic worlds.

Left to her own devices, Sierra prefers to bleach out her naturally-dark hair to a honey-blonde shade, but can't be bothered to make regular appointments for upkeep, and her standard wardrobe is what one might call 'military surplus-meets-thrift store chic'. Everything she owns is well-worn and thoroughly broken in, chosen for comfort more than fashion or any need to keep up with the current style. Regardless of attire, unless prevented by a mission, Sierra keeps her short, but neatly-manicured nails lacquered in some shade of purple at all times. She carries a gold-plated cigarette case in her pocket, but instead of being surrounded by the lingering stench of tobacco, a light aroma of grassy herbs spiked with cloves and cinnamon follows in her wake.

She has a trio of small tattoos clustered together on the inside of her left forearm, a white bear, a golden bull, and a black wolf. The back of her right hand is prominently inked with the insignia of the 12th Star Guards, and the nape of her neck adorned with a multi-petaled purple flower, rendered in a heraldic style. The boldest tattoo in her collection stretches from shoulder to shoulder across her back, a single thick line depicting the upper silhouette of a castle: not a fairy-tale demesne with pointed turrets and delicate flags, but the crenellated battlements of an impenetrable fortress, with a dark watercolor-style wash of ink bleeding down from the line for several inches before fading out entirely. The design is reflected on the back of her favorite jacket, thick leather with a fleece-lined hood, the exact same crenellated line airbrushed across the back in bold purple with a lighter-toned fade wash.
