It might not be the most ground-breaking prescription, but plain and simple is the key to nailing knitwear in the workplace.Avoid chunky textiles, which tend to bobble and moult, and invest in fine merino wool and cashmere (a de-bobbler or razor brushed over troublesome patches will help keep them pristine).

Prints should be avoided in favour of rich navy, grey and black hues.Stock up on these

in polo-necks, crew necks and V-necks, and your office ensembles will never go wanting of a smart sweater.

For a flash of personality, a contrasting-coloured cuff is a chic, subtle option.Alternatively, to highlight that your knit is from an altogether pricier set, a discreet logo or branded pocket will pop out to others in the know.

Save boyfriend cuts for the weekend, and keep your preferred styles fitted; long, trailing sleeves say loungewear not workwear.Lastly, read care instructions on labels, and store carefully over summer months to ensure your investment buys enjoy the longevity they deserve.

Four key pointers to keep you chic and cosy this winter:

1.Stock up on plain polo-necks, and use as a base layer underneath tunics and pinafores.Tucked into an A-line skirt, this style will also look timeless.

2.A short-sleeved knit is the perfect companion for midi skirts; make sure the style is fitted to the body so it doesnt look like a shapeless tee.

3.A V-neck lends itself to a preppy look; team with cigarette pants, brogues or loafers, and round spectacles.
