sex appeal,simpicity all i hope for in my clothes是什么意思?

I have often said that I wish I had invented blue jeans:the most spectacular,the most practical,the most relaxed and nonchalant.They have expression,modesty,sex appeal,simplicity - all I hope for in my clothes.这是原文,法国时尚设计大师Yves Henri Donat Mathieu-Saint-Laurent说的,赞美牛仔裤的.是说牛仔裤很有表现力,质朴又性感,是所有他希望自己设计的衣服能展现的元素.
