I think when family members (read Queen Victoria) criticized Helena's appearance they were speaking more of her manner than her looks. How one appears to others- perhaps she was ungraceful, or walked strangely, or had mannerisms that were more in common with men of her period- has a strong affect on a person's overall attractiveness. I've often wondered why Helena was called unattractive. However, a remark from "Victoria's Daughters" has stuck in my head. In a passage on Helena's tomboyish personality in youth, Packard remarks that Lenchen had to discard her favorite pursuits as unfeminine once she grew older. She liked athletic and mechanical activities- neither of which were acceptable for a Victorian princess. "Only once she lost this innocence during her teens would her life take on its coloring of apathy..." I know if I could not enjoy my favorite hobbies I would become a far less colorful person. Maybe the environment stunted Lenchen's personality in a way that showed outwardly.
