Theory, a post-modern fashion brand, was created in 1997 by andrew rosen and israeli-american designer elie tahari. Theory is a predominantly working-class, dynamic and timely working woman who seeks high-quality and classic designs, and also requires a tight current and white collar in fresh fabric. Theory wants to integrate personal taste, quality and elegance into a sexy, neutral design, so that ol no longer merely displays the man's hardness in his clothes to show his ability to work, but can integrate his mind and personality into his commuting suit, so that his clothes can also be worn on holidays and during his leisure activities, making the dress more liveable and comprehensive. The unique quest of young urban women for fashion has been met with a stylish, elegantly romantic, silky and sexy display. Each dress is carefully designed by a well-known hillary fashion designer in new york, united states, and handed over to a skilled clothing producer capable of producing it, each of which devotes all his heart and heart。
