I thought it might be appropriate to return to the misidentification of NB by Collins. It is said that one of the reasons for Collins mistaking NB for a female was the length of his hair. However if you check the photos in the gallery you will see that wearing his hair long was an exception rather than the rule.
It depends largely on how you define "long". I don't think it's being suggested -nor would it be true- that his hair was shoulder length. However, the front hair was long, it was also wavy -similar to, but softer, than the sharper styling of today in which the sides and back hair is cropped using clippers, and the top is allowed to grow. In both cases, if the head is down, and there's been no 'product' to control it, the hair will fall forward. Nevill's was a style favoured by most men of his age and social standing, but it required a good head of hair.
