Is your feature request related to a problem? Please describe.
The main purpose of this mod is to allow the player to walk around the house in cozy pajamas. However, the player does not have the option of wearing the default white shirt and red boxers due to it being replaced by the mod pajamas. It would be nice if the player could still choose to switch to the white shirt and red boxers while in the house, or include it as one of the pajama options.

Describe the solution you'd like
Allow the player to wear the default white shirt and red boxers as pajamas if they would like while in the house.
