If you're married, and you have a wife, and you really love your wife, is it good enough to only say to your wife 'I love her' the day you get married? Or should you tell her every single day when you wake up and every opportunity? And that's how I feel about my relationship with Jesus Christ is that it is the most important thing in my life.
I think the relationship is very tenuous between fashion and art. Many designers have built relationships with artists, which is not something I personally did. But it's true, sometimes you see artists working for a designer or a brand on some specific project or taking care of their environment and making an amazing store.
