You don't want to appear too try-hard or flashy. Besides which, your interviewer may have a very different opinion of a designer than you do. I'm no fan of Moschino for example, but I adore Ralph Lauren.
NO BROWN, RED OR ORANGE
Color has a big psychological impact on people, and that's brought into sharp focus in job interviews.
Studies have shown that wearing brown clothes gives the idea that you're old-fashioned and passive, and you won't be a forward-thinking, dynamic employee, whereas red has been shown to convey that you're too assertive or even rebellious.
It's too powerful and people – women in particular – often feel threatened by other women who wear red.
Orange meanwhile has been found to be the worst color to wear, as hiring managers feel it's unprofessional.
However, navy blue is often the best choice, as it inspires confidence. It's also less imposing than black, and gives the message that you're a friendly person.
NO VISIBLE TATTOOS
Be on the safe side and cover up any tattoos.
Research undertaken by St Andrews University suggests that the majority of employers feel tattoos are taboo and that 'ultimately, it does not matter what they think of tattoos. What really matters, instead, is how customers might perceive employees with visible tattoos.'
SKIP THE ON-TREND MANICURE
Just keep to a plain and simple manicure. This summer's trend for ladylike neutrals in rose pink is one current fashion that's acceptable.
Definitely don't go in with chipped varnish. It sends a message that you're sloppy when it comes to the details and possibly that your time-keeping skills are going to be terrible if you couldn't even find the time to do your nails beforehand.
AVOID HEELS IF YOU DON'T USUALLY WEAR THEM
If you can walk easily in high heels and they're going to make you feel good, then go for it – feeling confident is vital for job interview success.
But if you can't comfortably walk in them, you're going to give totally the wrong impression when you wobble into the room. It's far better to wear smart flats.
NO STATEMENT EARRINGS OR ALTERNATIVE PIERCINGS
Again, avoid anything potentially distracting. Keep jewelry to a minimum – maybe a single statement necklace with stud earrings.
Remove any alternative piercings that aren't in your ears.
