First, what can be verified.
The red knit with rows of white sheep and one black sheep was made by Sally Muir and Joanna Osborne, who founded Warm & Wonderful in 1979. In June 1981, after her engagement and before her wedding, 19-year-old Diana wore the original physical jumper to polo. Palace letters requested repair or replacement after cuff damage, and the makers supplied a new one. The 1983 appearance shows the same design, but a different physical jumper: the replacement.
What kind of claim is ‘outsider’?
In English, ‘black sheep’ can mean a person treated as different or troublesome within a group, and later commentators repeatedly read the motif as foreshadowing Diana’s royal position. Yet no first-person source reviewed here confirms that intent. Maker Sally Muir later suggested that Diana may simply have liked a playful jumper and may not yet have understood clothing as a public language. Its meaning was not necessarily fixed at selection; it accumulated through wear, press coverage, later biography and cultural memory.
Separate documented fact, maker testimony, later interpretation and unverified wearer intent. The symbolism can be read; deliberate outsider messaging cannot be asserted.
