If you only do one thing this week … make a good first impression

Giles Morris, writing in The Guardian, has kindly quoted me in his article following my interview with him recently. Giles writes:

The apparel oft proclaims the man, as Shakespeare once observed, and this hasn't changed much since we all went around in frilly ruffs and bodices.

The solution is not to opt for clone-like business wear. Lucinda Slater of image consultancy Best Foot Forward says: "Everybody wants to look professional, but there's got to be something extra." Your clothes need to demonstrate "characteristics which are special to you and make you stand out".

A distinctive tie or a jacket with colourful lining are great ways for a man to show individuality, Slater says. But she counsels against novelty socks or jazzy cufflinks. "People would think, 'What a joke'. It undermines your credibility."

And style gaffes are not limited to the boys. Women frequently let themselves down with poorly fitting clothes, visible underwear and worn heels, Slater says. Spaghetti straps and flip-flops also get the thumbs down – evidence of the confusion smart-casual dress codes can sow. "People don't know what is appropriate for work and what is appropriate for home," she says.

Her top tip is to think first about what qualities you want to display when you are at work. Then go through your wardrobe, try on each piece and look at yourself in the mirror. Ask yourself honestly if you see those qualities in whatever it is you're wearing. If the answer is no then the item in question should be consigned to the weekends.

And if that leaves you with rather a large weekend selection, take heart: you should be able to make a good impression next time you're at the supermarket.
