that post about “how to look like you kill people for a living” bothers me mostly because no assassin in their right mind would go about their job looking like a punk rock womanizer hobo

a true assassin would keep themselves very neat and unassuming, with nice, subtle clothes and a fresh face

the very best of assassins would keep themselves youthful and angel-faced and doe-eyed. the leather accessories would be retained, but all leather would be italian and in deep brown or in smooth delicate calfskin

(tailored blazers + fuller skirts + satchels all have ample space to hide whatever “tools of the trade” one may need)

these superior assassins wouldn’t need “worn-in” clothing for movement; they could finish off a job with a bare minimum of effort. still it doesn’t hurt for chosen closing to have a good deal of stretch. leotards in black can also be worn under clothing both as underwear and to be a quick change of clothes if you’re being followed; you can pass it off as a tank top or leggings underneath a skirt or a jacket, respectively.

blood drips would be kept to a minimum, for obvious reasons. proper assassins are never messy. 

essential accessories: phone with powerful processor for communications and tracking, small laptop for getting into networks and further tracking, gloves (preferably driving gloves as to not seem suspicious when searched; mine are pale calfskin, which is delicate but easy to clean) for the messy work, wet sanitizing wipes (also discreet and helpful for the process), sunglasses (don’t wear these all the time, else you’ll risk looking both suspicious AND rude), makeup and a beanie hat (both of which do wonders when you need to look a little different quickly), tissues, lock picks, chargers for any electronics, and a great deal of guile

you may want to wear a bluetooth jawbone or whatnot for easy access to communication but these are usually very obvious, flimsy, and they fall off much too easily (which could be FATAL for you during a chase. stick to headphones with a mini microphone or just use your phone)

if you INSIST upon the ominous wearing of blood, keep it to a minimum and make sure it’s tastefully done; dribbled down your shirt is much too obvious. subtle placement, such as under your fingernail tips or staining your knuckles (and if you MUST have blood on your face, have it at the corners of your mouth. and i still discourage this odiousness)
