The part where both sexes are asked to "step it up" to the same level of "dressing up", which is usually considered appropriate and expected in this kind of events anyway. This dress code description is literally what most people would imagine when told "award ceremony attire". But the headline read as if women were singled out and unnecessary sexualized.
One could argue they are clumsily trying to ask for the same level of dress. At least in context, which is the problem with the quote. They describe it in a salacious way which leaves no room for argument.
