Tom Ford says "powerful" fragrances work better in the winter.

The designer says it's important to match your perfume to the weather and when it's cold outside he thinks a string scent works much better.

He said: "I always prefer rich and heady scents for winter, as they don't get lost among the Christmas smells of pine and log fires. Powerful scents like my latest scent Violet Blonde - with orris, cedarwood and violet leaf - will help you stand out.

"Violet Blonde expresses a kind of femininity that is formal, luxurious and polished - a classic, Hollywood glamour. I wanted the word 'violet' in the name, because it has a fascinating pull. It's shade associated with royalty - you almost cannot look away from a true violet shade."

The former Gucci creative director also says it doesn't matter if you wear different perfumes throughout the day and night.

He said: "Layer one or two perfumes to create a sense of depth and richness - it's perfect for the party season. I usually end up wearing four or five different scents by the end of the day, as I don't change my fragrance for the evening - I simply add to my existing one."
