Another suggestion: Martial artist's themed clothing sets.
I was just thinking that the player character is able to attack while unarmed and deal damage so maybe a few martial artist's themed clothing sets might be an interesting addition ?
Calling them sets as the clothing is a visually similar - not because it gives any bonuses - other comments by Indivi have indicated that they want clothing to primarily remain a visual / vanity only thing.

Set One: Kung Fu Set
Long black shirt (extends below the waist), Black pants, black slip on shoes with a white shoe sole.
Might not be the best description but think along the lines of the clothing work my kung fu masters in the Ip man series of movies as an example.

Set Two: Karate Set
White long sleeved shirt, White Pants, Black belt
Pretty sure most people know what a karate uniform looks like.

Set Three: Monk Set
Orange Robe, Orange Pants, Dark orange sash.
Think along the lines of Tibetan warrior monks .
---
Set Four: Ninja Set
Dark Shirt with dark netting underneath, Dark Pants with Dark netting underneath, Ninja mask.
Ninja mask is already in game and the shadow set from lust doll classic could work for the rest of the set with the bonuses removed.
