That looks right, yes.

But - if it doesn't look right on the fabric then you can let it hang free or secure it some other way.

I find that when I am sewing the top of the aprons I need to lift the inner edge of the under apron pleats very slightly to stop them rolling outwards.

It is only about 1/4 of an inch, so there is a very slender triangle of fabric held above the edge of the aprons, hidden within the waistband, but it makes all the difference to how the pleats hang.
