In almost all modern offices, it’s a case of anything goes these days – though even the most liberal businesses will still look unfavourably on racer-back T-shirts, mini skater skirts, an over-indulgence of cleavage and anything that looks like you’ve turned up in fancy dress. There are still some professional workplaces which demand decorum and old-school smarts – and it is here that a very well-cut trouser suit still scores points. To bring it into the 21st century, go for tailored shorts and a nipped-in jacket instead of mannish trousers. Or go for this season’s hot buy – a skirt suit with a full skirt and a curvy jacket. Proper heels, glossy hair, polished make-up, perfect nails and an expensive handbag will do the rest. But wherever you work, bear in mind a wise word from one magazine fashion editor recently, “People are simply getting sick of this dressing down at work… I mean, you can't work hard in flip flops." If you really want your brain to work, your clothes should too.
