The Vanity Slots on the Inventory window are located at the far right and left of the Character (Next to the Equipment Slots) and are only for aesthetic purposes and do not provide Stat bonuses.
You can Equip either Crumb shop items or in game items such as Crafted and Dropped Equipment
Tips to help with character styles
- Equipping a 2H Weapon in your vanity slot while wielding a offhand item does not remove the Shield from view (looks like the player is hold a large weapon and a shield at the same time)
- Equipping a melee weapon over your Long distances weapons looks like the Melee weapon is casting (Magic Sword)
- Hovering over a player character will show the Armour and weapons they are currently using
