Looking charming and beautiful is the sole aim for any hair-do. If such wasn't achieved after a particular hair-do, one would either start blaming themselves for not going to a better hair stylist. That's the major reason why there's something called "insight", have an idea of what braid you want and be sure the coif will fit your type of face.
This braid on Queen looked somehow wig-like. Had a friend that wears such wig and you won't even notice it as such. The front weaves were closely plaited making it very hard to see the parting. It gave her a spectacular look in a very stylis way.
