There's no room for slackers with this season's sharp styles as tailoring takes centre stage. Nevertheless, military needn't mean masculine, as proved by this sexy Temperley dress (£590, www.netaporter.com). Vary your silhouette by covering up with a cape – the brass buttons on this striking Jaeger number (£499, www.jaeger.co.uk) are a suitably soldierly touch that add the definition necessary to prevent you being swamped by the fabric. Pair it with a slim-fitting pair of trousers or skirt. To add a tough edge to other outfits, these sturdy but chic boots (£249, www.toast.co.uk) and dashing leather gloves (£24.99, www.riverisland.co.uk) should pass muster.

Anyone with a family tartan should be feeling very smug this autumn, as designers have gone criss-cross crazy. For the rest of us, there are countless variations to suit. Make it part of your daily wardrobe with a coat: this belted mac is a handy style short-cut (£100, www. warehouse.co.uk). A tartan blouse such as this bargain number (£10, www.matalan.co.uk) will look equally good dressed up with a skirt or down with denim. And while red is the colour of the season, this blue-and-black jacket (£35, www.newlook.co.uk) gives you another option. For a punkier edge, pick up this tote (£55, www.frenchconnection.co.uk).

Take your inspirationfrom none other than Her Majesty herself, but avoid state jewels and opt for relaxing-at-Balmoral mode. A chunky knit such as this Topshop Fair Isle jumper looks cosy and cute (£32, www.topshop.co.uk), while this checked A-line skirt is a pleasingly subtle alternative to tartan (£50, www.lauraashley.com). Finish it off with the ultimate in landed-gentry chic, a crocodile clutch (£245, www.twenty8twelve.com) and a headscarf knotted below the chin for a demure look to make your granny proud. If you can't afford the iconic Hermès silk square, head to Aldo for a bargain version (£15, www.aldoshoes.com); the touch of leopard print will keep it modern too.

A high-brow take on boho, the trick is to look as if you are too busy working on your latest oeuvre to pay too much attention to what you are wearing. A vintage-looking tea-dress such as this floral Whistles design (£140, www.johnlewis.com) should form the base of your outfit, paired with an oversized cardigan (£235, Tibi from www.netaporter.com) for an artfully dishevelled look. Keep warm with woollen tights or – if you're lithe of leg and feeling adventurous – stockings (£85, with vest and knickers, www.day.dk). Accessorise with this 1920s-style leather cloche (£29.99, www.hm.com) and an obscure Penguin Classic.
