Fashion is psychology: Stella McCartney

British designer Stella McCartney believes her designs reflect her personality and so, she is always conscious of making relevant yet timeless pieces.

The 42-year-old thinks about her "holistic sense of self" when working on new pieces, and concentrates on creating clothes relevant in today's society, reports contactmusic.com.

"Fashion is psychology, so there's a whole holistic sense of self that I'm thinking about when I'm designing. And of course, I want clothes to be modern and cool and relevant," she explained to The Observer newspaper's The Fashion magazine.
