The answer is her nose and ears.
Unlike most parts of the body, the soft tissues of the nose and ears continue to grow throughout a person's entire life. This is because these areas are composed of soft tissue surrounded by cartilage. As we age, the cartilage and soft tissue continue to accumulate cells, resulting in a gradual increase in size. This is true for both men and women. This continuous growth is one of the reasons why older individuals often appear to have larger noses and ears compared to their younger selves.

Example: Notice the subtle changes in the size and shape of someone's ears and nose as they age from their twenties to their eighties. The increase in size is noticeable over time.

Cellular Growth: The continual accumulation of cells within the soft tissues of the ears and nose is responsible for their ongoing growth, a process that isn't replicated across the body.
As noted in a reference, "When you look at someone when they're 80 vs. when they're 20, they'll have more cells in their ears and nose." This observation directly supports the assertion that the nose and ears continue to grow throughout a person's lifetime. This growth is independent of overall body growth patterns.
