I think models like Shalom and Erin O‘Connor, like modern day Karlie Kloss, are all 6 feet (2Metres) and over, the IDEAL catwalk height. Makes them very, very striking.
All classic designers like the models to be as thin and tall as poss, they care less about ‘ethereal‘ or ’sexy kitten face’ or anything like that! They want them vaguely symmetrical, bulimic, on a heroin diet, and as tall as you like in your bare stockings!
My source for this is an agent who worked for one of the top ones in London!
