Distance for Strokes within a shape but also on the outside?

Question

Hello,
I would like to ask, how do I go about creating a stroke, but i want it on the inside of a wavy line, but a little further in the shape.
Just say for example a blue rectangle and say I would like for the stroke to be white, but more inside the shape rather than just near the outer edge of the rectangle is there a way opf setting the distance.
How about in reverse - I know there is convert to shape - but what if the shape is curvy or wwavy?
Is this able to be done also?
Thankyou,

Either Object>Path>Offset Path
Or as an Effect you use Effect>Path>Offset Path
a negative number moves it inside a closed path a positive moves it to the outside of the path
if you use the Appearance panel and add new strokes you can have one inside and one outside or serval inside and several outside.
