Remember in the 80s classic film 'Working Girl' when Tess McGill (played by Melanie Griffith) gets rid of the chunky jewellery and the over the top hair, and instead dons a tailored jacket and, well, slightly less big hair? That was the moment she started being taken seriously and climbing up the career ladder. We're not saying that you can't have some fun with fashion at work, but don't underestimate the power of a power suit. Here five women in the spotlight show how you can take power dressing to the next level. Don't worry, there's no need to resort to 80s fashion to make a statement (although you can if you want to)! Just take a note from these style icons instead...
The Queen
Queen Elizabeth II isn't just the longest-serving monarch in British history, she is also one of the most stylish. The Queen knows the value of super-smart tailoring and always wears clothes that suit her to perfection. But tailored doesn't mean tedious; bright coats and colourful scarves liven up any outfit. And don't forget an important woman's best weapon - sensible shoes!
Amal Clooney
We may not have Amal's top notch job as a human rights lawyer (or her handsome husband), but that doesn't mean we can't steal her fashion tips. George Clooney's other half favours skirt suits, bright handbags and timeless accessories - stylish sunnies are an absolute must. True, many of her outfits are designer but her classic red lip won't set you back a small fortune.
Claire Underwood from House of Cards
Have you watched Netflix's political smash hit House of Cards yet? Robin Wright plays power-hungry Claire Underwood, wife to Frances Underwood (Kevin Spacey). When you're trying to take over Washington DC, your work clothes have to mean business and Claire's wardrobe doesn't disappoint. Effortlessly chic and seriously polished, Claire shows that by keeping dresses simple and lines clean, dresses can be pretty and powerful.
Hillary Clinton
If you find a look that works for you, stick with it. At least that's what Presidential hopeful Hillary Clinton has done with her one-tone trouser suits, a style that she has favoured since her days as First Lady in the 90s. Will she take her signature workwear all the way to the White House next November?
Stella Gibson from The Fall
Just because you find yourself in a male-dominated field, that doesn't mean you can't opt for feminine fabrics and sultry shapes. Just take a cue from Detective Superintendent Stella Gibson (Gillian Anderson) from the BBC drama The Fall. Pair a silk blouse with fine gold jewellery to dress it up or team with jeans and heels for a more low key look. Perfection.
