We have seen what is his counsel to the actor.

He preaches in the same key to the scene-painter and the maker of costumes.

Let it be that of a man of taste and no more: no ostentation and no gilding, unless the situation expressly demands the contrary.

Under robes that are overladen with gold lace, I only see a rich man; what I want to see is a man.
Pretty and simple draperies of severe tints are what we need, not a mass of tinsel and embroidery.
