The big issue will be that there is no way these publications could make anyone happy with defining tznius.
Indeed, though some of the examples in the article are beyond ridiculous (women's shopping spree for example).
Much of tznius is subjective. Anyone who thinks it is a bunch of lines missed the boat.
The hardest thing is to get people to understand and realize that. Especially in today's day and age, where people are looking for brief, instant answers, rather than actually immersing oneself in the topic and understand it in a way that one actually gets their own sense of tznius.
