A clumsy figure, a large waist, are no doubt very ugly at twenty, but at thirty they cease to offend the eye, and as we are bound to be what nature has made us at any given age, and as there is no deceiving the eye of man, such defects are less offensive at any age than the foolish affectations of a young thing of forty.
Everything which cramps and confines nature is in bad taste

Context

“A slender waist has its limits, like everything else, in proportion and suitability, and beyond these limits it becomes a defect. This defect would be a glaring one in the nude; why should it be beautiful under the costume? I will not venture upon the reasons which induce women to incase themselves in these coats of mail. A clumsy figure, a large waist, are no doubt very ugly at twenty, but at thirty they cease to offend the eye, and as we are bound to be what nature has made us at any given age, and as there is no deceiving the eye of man, such defects are less offensive at any age than the foolish affectations of a young thing of forty. Everything which cramps and confines nature is in bad taste; this is as true of the adornments of the person as of the ornaments of the mind. Life, health, common-sense, and comfort must come first; there is no grace in discomfort, languor is not refinement, there is no charm in ill-health;” source
