WOMAN OF THE WEEK. To Miss Marjorie Stewart, the actress, who has scored a success in the new West-end play 'Little Strangers,' belongs a distinction unusual in these modern days. She is said to have the smallest waist of any woman of her height in London. Although she is five feet six inches tall, Miss Stewart's natural waist measurement is only twenty one and a half inches. With the return of Edwardian fashions and smaller waistlines, she is the subject of considerable envy. A daughter of the late Sir Francis Stewart and of Lady Stewart, Miss Stewart does not come of a stage family, but made her debut in amateur theatricals at the age of five!
