Washington does not require a permit to open carry with the exception of being loaded in a vehicle (must have a CPL to be legal). If you have a CPL then you are legal to conceal. So you're covered both ways. I do not understand the question fully but I hope that answers what you're trying to ask. If you are open carrying, then the pistol is visible i.e. not covered by anything, if you cover it with a shirt or jacket you are concealed carrying and need a CPL to remain legal.
