Gabrielle stands a little over six feet tall, with a long, powerful frame that makes her difficult to overlook even when she is trying not to draw attention. She carries herself loosely rather than with aristocratic stiffness, shoulders relaxed and chin often tilted with an air of quiet appraisal. Her proportions are generous without being soft, with broad shoulders, a full bust, pronounced hips and long, strong legs. There is something physically assured about her, the impression of a woman who knows exactly how much space she occupies and sees no reason to surrender any of it.

Her face is long and expressive, with high cheekbones, a strong jaw and a broad brow above large, very dark brown eyes. Her gaze can be remarkably warm when she is amused, but when her expression empties those same eyes become unsettlingly still and difficult to read. She has a broad nose, full lips and a wide, striking smile, with slightly prominent canines that only become unmistakably unnatural when she bares them deliberately. Her deep brown skin is exceptionally smooth and cool to the touch, taking on a faint blue-black lustre in cold or moonlit surroundings.

Gabrielle's hair is thick, black and abundant, most often worn in long twists or locs that fall well past her shoulders. She varies how she arranges it, sometimes letting its weight frame her face and sometimes drawing it up to expose the long line of her neck. Her ears are usually decorated with gold, silver or dark-stoned jewellery, and she has a particular fondness for pieces that look old because many of them genuinely are. Her makeup tends toward dark eyes, defined brows and rich lips, dramatic enough to complement her features without disguising them.

Her hands are large and elegant, with long fingers and carefully maintained nails that she usually keeps dark and slightly pointed. There is considerable strength in her arms and back, although little of the exaggerated definition that would advertise it at a glance. Her movements are measured and fluid, occasionally becoming unnaturally precise when she stops paying attention to appearing human. When completely motionless she can be disconcertingly still, without the little shifts of weight, breath and nervous movement expected from a living body.

Her taste in clothing runs unmistakably gothic, favouring dark fabrics, strong silhouettes and garments that flatter her height rather than trying to diminish it. Velvet, lace, leather and fine wool appeal to her, as do high collars, plunging necklines, fitted waists, long coats, boots and jewellery with an antique or funereal character. Black dominates without being compulsory, accompanied by oxblood, plum, ivory, midnight blue, dark green and occasional flashes of precious metal. She dresses with enough sensuality to suggest that modesty has never particularly interested her, but rarely looks careless.

Seen as a whole, Gabrielle is beautiful in a way that becomes more unsettling the longer she is observed. She is too poised, too still when she chooses to be, and occasionally watches the pulse in someone's throat rather than their eyes. Her warmth and animation can make those details disappear completely until hunger, anger or simple carelessness brings the predator back to the surface. Even then, Gabrielle seldom looks feral; the more dangerous she becomes, the more controlled she tends to look.
