INTERVIEWS can be extremely nerve-wracking affairs, especially if you're in the running for your dream job, so doing everything you can to boost your confidence is a good idea - and that includes your outfit.

"A job interview begins with first impressions, and your clothes and grooming are a key part of this," says Amber Butchart, a fashion historian and expert who has appeared on the BBC's Great British Sewing Bee.

Butchart is working with careers app Debut on the 'Dress to Impress for £10' campaign, which starts on Wednesday and involves more than 650 charity shops.

Representing 42 different charities, each shop will curate a selection of workwear staples priced at £5 each in order to help jobseekers find affordable interview clothing.

"Overall, it's really important to wear something you feel comfortable, confident and smart in," Butchart said.

"Your clothes can affect your body language and the way you project yourself to future employers, so it's of utmost importance that you feel like the best version of yourself."

Here, she shares her top tips for success... Research the dress policy of the company, don't be afraid to wear colour... but not too much, a suit isn't essential as smart separates can be better than an ill-fitting or poorly-made suit; if in doubt, dress up; choose your shoes carefully and mos importantly be presentable.
