Break out the eighties look:

So, it’s officially time to ditch the fail-safe LBD for eye-popping colour. Be brave and ditch the dress altogether – disco pants (yes, American Apparel’s best-sellers are back) and a polo-neck blouse are how the fashion-forward will do festive style.

Wear a decorative coat:

If the Christmas party season were an item of clothing, it would be Prada’s golden brocade coat. There is, categorically, no better evening coat. Try Hobbs, Jigsaw and & Other Stories for strong alternatives.

Flash your underwear:

Thanks to Prada, Dolce & Gabbana and Isabel Marant, big knickers have never been so chic. Wear your high-waisted, Fifties-style pants with a matching bralet beneath an ephemeral summer dress, as spotted in Céline’s pre-fall look book.

Scale down your evening bag:

Don’t lug the workbag into the party. A teeny cross-body bag (Fendi obviously sets the bar when it comes to these), or minaudière on a delicate chain strap are now all you need.
