Late to this thread, but I can't resist chiming in... My answer to what wear in an "emergency house exit in the middle of the night" - normal clothes!
I agree. Way too much over thinking with scrubs as your get out of the house clothing wear.
Keep a good set of clothes next to your bed or by the door and grab them on the way out. Simple, easy and in the end, everyday clothes are much more durable, warmer and versatile then scrubs will ever be.
