Jacket can be bought online, but watch out for scam sites, they can be found in leather, fake leather or sheepskin
Vest is a dark blue suit vest (formal style, bottom on front sides in V shape)
Scarf, red, very worn, tattered, and thin
Black denim jeans, again dirty
Dirty white t-shirt ("HAVE A NICE DAY", HAVE A on top, NICE DAY on bottom of yellow smiley. [shirt confirmed!])
Also, looks like there's a thin black & white striped long sleeved shirt under the jacket, shows under the cuffs of the jacket, probably the base-layer, under the above mentioned t-shirt.
Some kind of ankle wraps, similar to Daryl (torn cloth on right ankle, old brown belt on left (see pic)
Black belt, antiqued/dirty buckle ( 2 hole, roller-type) AND brown leather, D-shaped buckle(pics attached)
Boots are really dirty, dark brown industrial work boots (same pic as the wraps for better view)
Gold teeth on the bottom (looks like 4)
Oh, and the knives, they are Mtech Raptor, which have short lanyards added, and the etchings are removed/covered up, dirty of course, 18" long
All of them should be pretty easy to source online, or local stores, thrift shops, etc.
Attached pictures for reference. HOPE THIS HELPS!
