FACE: Face is extremely thin and slender, with a prominent outreaching rectangular chin — overall it resembles the shape of a skull. Eyes are a deep brown, have epicanthal folds, and are shadowed with extremely heavy eyebags. They also have anisocoria, with the left pupil being bigger and the right pupil being smaller. Eyebrows are relatively thick and a bit scruffy. Mouth is prone to visible wrinkling during even the slightest displays of emotion, particularly crowding at the chin directly under the lips.
HAIR: Black in color. Decently curly, resting at a 3a type texture. It’s cut shorter at the front, with the back being longer and flooding down past their shoulders — it’s more or less an accidental overgrown mullet. Always looks a bit wet or 'scraggly' due to them being flakey about caring for it properly.
BODY: Roughly 5’0ft tall. Notably very skinny and lanky. Their left leg is somewhat shorter than their right one, and so they usually bend the latter to maneuver themself around. Has some light body hair, particularly prominent at the arms, legs and chest.
MAIN OUTFIT: An important thing to note is that their outfit is… actually colorless, predominantly. Whether this means its just like a monochrome grey arrangement that’s only embellished in artwork and writing for intrigue or if it’s all somehow enchanted to change hue chameleonically, who knows! But the typical 'blue' color scheme is mostly enforced when meeting them in the control room, otherwise changing arbitrarily: it appears more sanguine in the Summer District, greener in Spring, etc. The only colors that stay fully consistent regardless of environment are the green flourishes on their vest, suspender straps and shoes.
To actually describe the structure of it all, though… They don a sundial-like beret with a circular ring of roman numerals present near the edge. Top of the outfit is fairly cluttered… First they have a short-sleeve dress shirt with sharp, frilled hems at the sleeves, and an angular white collar with a brooch hooked in the center bearing a "I" numeral. Over this they wear a darker vest closed up by a green, planisphere-esque gemstone pendant, with smaller diamond-shaped star clasps further supporting this — the back of the vest features a sewed-on depiction of the constellation Fornax, with the text "FACILIS DESCENSUS AVERNI" right beneath it. Over THAT they wear white striped suspenders that resemble roman pillars, anchored to their pants by large green half-compass shaped clips. Arising from those are two pale sashes, yet again decorated with a linear ascension of roman numerals. These wrap back around to the opposite side of their suspenders, forming a finalised C shape. Their pants are layered, too — the lowermost layer is a pair of jeans, over which darker, looser chaps are worn. Socks are pale and striped, and stretch far up past their ankles. Shoes are an odd commixture of sneakers and dress shoes, with angular 'tongues' and slight heeling. A sun emblem dwells by the back of the shoe. They typically wear offwhite opera style gloves that stretch past their elbow.
Cane is customised and maintains the roman pillar motif. It has a major curvaceous valley right before the handle, with the handle itself bearing a cushioned membrane. A beam runs upwards from the base of the handle, which grants them extra elbow support. Downward from the same origin point is an enchanted kamal-like charm that can be reeled up and down to weigh the cane down or make it lighter.

GENERAL FASHION STYLE: The primary word I’d use to describe it is 'stuffy'. Even though their story era paradigm is remarkably much more confining than their usual style of dress, they’re just regularly drawn to very tight-fitting clothing. Dress shirts, vests and jeans are a staple of their usual couture. They also quite enjoy 'archaic' garments like suspenders, brooches or that one breed of tiny thin scarf. They’re also fond of necklaces, though specifically very loose ones — anything that’s too tight on their neck becomes uncomfortable. Same thing with bracelets that are too tight on the wrists.
They’re usually not too picky with textures of clothes, though tend to steer clear of overly fluffy or woolly garments. They also usually prefer wearing things that cover their body in full, or at the very least layering to achieve that affect — if not wearing a long-sleeved shirt, they’ll compensate by wearing extremely tall gloves; they usually prefer wearing long socks that swell up to their knees; etc… They’re not the most fond of showing off their limbs.
A frequent setpiece of their clothing is, simply, a funny hat. Any of the wide-brim variety work — though they do have a special fondness for cowboy hats and fancy berets. They also like accessories that glimmer and shine, though these are worn in moderation because they’re shy, heh — they particularly like green gemstones of any kind and deem them 'lucky'. Note the various green embellishments on their paradigm as demonstrative of this.
The color schemes of their fits are honestly still very ambiguous in my mind but one thing I can say is that they gravitate toward extremely dark clothing, with green being a frequent definitive color. They also, generally, like wearing striped clothes.
Though their style could hardly ever be deemed unfashionable — in fact, they straddle the line between respectable formality and homely elaboration quite well — though there’s an element of disorganisation and off-kilterness in their outfits that adds an odd je ne sais quoi feeling to how they dress…

POSTURE AND MOVEMENT: More or less defined by… well, tremulousness. Any kind of movement they make is characterised by jitter and instability — they’re prone to slipping if walking forward too harshly, stumbling whilst simply standing, having extremely shaky hands, constantly having to regrip things… Their lack of balance comes from a combination of eternal nausea and lightheadedness, and the difference they’ve got in leg lengths. Part of it also comes from an impulsive need to gesture with their hands, which completely displaces them, naturally. They often seem to overestimate their own strength, often attempting wide sweeping motions only to be caught in a series of swerves and hops instead.
Their face is extremely malleable and easy to contort. There’s a lot of pressure in the way they move their brows and mouth, often widening their eyes, gritting their teeth, grimacing strongly, etc. As a result of this, their face is often claimed by heavy amounts of creasing and wrinkling.

VOICE: Would be high-pitched were it not for how throaty and raspy they sound. Their voice is extremely hoarse, and prone to arbitrary breakage, whether resulting in outright splintering of their words, random quietness, bubbling or squeaking noises arising from the back of their throat… Because of this, they’re frequently intentionally shifting their volume, though it hardly works as compensation, instead ending with them either yelling inappropriately or speaking in a far too low whisper. They usually stick to keeping their voice low, since loud noises contribute to their nausea.
Their intonation is just as unstable as their audibility, with them often stressing syllables strangely, making plain phrases sound like questions and inversely making questions sound like concrete statements. A stutter is present, mostly audible with r’s, n’s and similar consonants.
