Andy is "significantly taller?" From what I've seen in photos, Candy was a whole head taller than Warhol. If Warhol was 5'11, Darling had to be in excess of 6ft herself.
And FYI, Darling was transgender and identified publicly as a woman from her late teens onward. Referring to her or any trans woman with masculine pronouns (or as a "he/she") is inappropriate and inaccurate. Plus, she is listed at IMDB as an actress. She was a she, period.
