Run&Gun has option for stacking armors that have the Custom Fit feature (and maybe has to be of the same manufacture). All the coats that act as outer layer adds 1/3 of their AV to the base layer, but but not all brands have coats to add to the suits.
Does anyone house rule that as long as a base layer is Custom Fit you can stack it with a Custom Fit coat of another brand?
And in extension, perhaps allow any base and outer layer to be custom fit (within reason) to be worn together and stacked? Here I'm thinking of combinations like a base layer of Form Fitting Body Armor or Armor Vest or Armor Clothing stacked with an outer layer of a Lined Coat or Armor Jacket or any one of the High Fashion Coats.
Since the rule appears to be +1/3 of the outer layer, it should be pretty simple if you can find an armorer who can custom fit it for you.
Thoughts?
