I think I must have seen that Marc Jacobs perfume bottle too many times. At least daisies apparently symbolise youth, simplicity and innocense:
"During the 18th century sending flower messages based on a Turkish secret language of flowers became popular. This was known as sending a 'Persian Selam' - a coded bouquet to reveal your feelings of love or attraction. The Victorians became very knowledgable in flower language and chose their bouquets carefully. Flowers gave them a secret language that enabled them to communicate feelings that the propriety of the times would not allow, there were strict restraints on courtship and any displays of emotion."
"Daisy - innocence and modesty - chanting 'he loves me, he loves me not' as they plucked the petals from a daisy was how Victorian girls discovered whether their suitors were true or not. Northern girls once believed that if they closed their eyes and picked a handful of daisies, the number they held would foretell how many years it would be before they married.
Be careful which daisy you send, as the Michaelmas Daisy means farewell."
The daisy also had a powerful religious connotation because of the widespread use of the image of the Madonna and Child, The Virgin Mary and the Christ Child, Jesus.By the late fifteenth century the daisy was a symbol of the innocence of the Christ Child. The daisy, less exotic and pretentious than the lily, was thought by some to be a more fitting symbol for the baby Jesus.
Since that time, daisies have been associated with children and the innocence of childhood. For young women, a bouquet of daisies denoted a particularly innocent, pure and chaste expression of love. During the 60's, the daisy was nearly as popular a symbol of the peace movement as the peace sign itself.
It's probably a good thing society has dispensed with this sort of symbolism. If we still had to send out signals via flowers, fans or dress no doubt I'd mix it up and accidentally give my most seductive signals to old dowager duchesses and retired colonels.
