Here's a quick screenshot of the WIP inventory screen and the map UI.

Players can equip clothing/armor on their grey paper doll. The weapons/items player has in his hands are shown in the boxes on the sides of the doll.

If the player is a female character then the doll is a female. The female and male dolls can use same pictures for equipment or they can be specified via simple file naming conventions:
tshirt
tshirt_f

If "tshirt_f" is not found, the female doll will use "tshirt". So the code is a bit sexist as the male version is the "default" .___.

The dolls/mannequins themselves are customizable by replacing the default mannequin .png files with new pictures. The default mannequins are supposed to be extremely generic grey statues.

The item stats are shown via popup tooltip that actually shows the content of the txt file that defines the items. So they are pretty easily formatted.

The clothes shown are probably the starting clothes for the player character.
