I think what hurts the most to people who don't like Rodarte's aesthetic is the wearability, technique and price-tag factor to their clothes. These girls are beyond that and that's why they caught people's attention in the already conventional American fashion scene. They are very capable of doing gorgeous gowns like Natalie Portman's dress in the 2009 Oscars, but they choose not to do the safe way and show us every season a journey to this fantasy world they have created. Every show, while might not have the best techniques of construction but at the same time we have to remember that most of this clothes are handmade, are really inmerse in this emotional atmosphere that really sets them apart from other designers.
It's just not another commercial showcase of what you should wear next season, that might be the example of Herve Leger. It's beyond that. Very few people are capable of creating a fashion show. One perfect example of this is Alexander McQueen, though he added couture-like techniques, but this girls are growing and what they lack of construction, they have it in emotional creativity and that's why they are like a rush of fresh air in the New York scene.
