Stella McCartney thinks women's fragrances should allow their personality to ''shine''.

The designer - who released her first perfume in 2003 - admits her new scent Lily has an ''almost aggressive'' side to it, which is similar to how she works.

She said: ''Everyone wants a fragrance that lets their personality shine through, not one that gives them a headache.

''I've been thinking about this perfume since my first scent Stella launched in 2003. I love lily of the valley - it was in my wedding bouquet - but I wanted to match its femininity with something tough, so I added truffle and moss, which is almost aggressive.

''This is similar to how I work with my ready-to-wear collections.''

However, the British sartorialist was also keen to make sure the bottle matched the perfume.

She told UK's In Style magazine: ''I went for cut glass and cut crystal, as they create an interesting texture, while the pink juice is subtle and delicate.''
