She was full-bodied, vigorous; and yet not so full-bodied as she seemed.

I remember with what surprise, when we arose from table, I noted her slender waist.

At that moment I got the impression that she was willowy.

And willowy she was, with a normal waist and with, in addition, always that informing bodily vigour that made her appear rounder and robuster than she really was.
It was the health of her that interested me.

When I studied her face more closely I saw that only the lines of the oval of it were delicate.
Delicate it was not, nor fragile.
