The fashion briefing

Look of the week In head to toe Miu Miu, Chloë Sevigny used the LA Prada book launch to give us a fashion lesson in how to style next season’s underwear trend. Remembering that a little flesh goes a long way, Sevigny teamed her bra with both a blouse and cardigan, ensuring not too much skin was on show. The key to this look is a straight back – tummy creases will be sure to ruin the whole thing – and a calf-length skirt. Minis will not do. Photograph: guardian.co.uk

Instant update: Can’t get hold of the Chanel Jade nail varnish which is currently sported by celebrities and fashion editors galore? Head to Urban Outfitters, which is today launching its Peppermint polish. The only difference is the price. £6, urbanoutfitters.co.uk Photograph: guardian.co.uk

Splurge Why not cheer up gloomy autumn days with this rainbow-striped Tara Matthews scarf. The generous width will ensure plenty of warmth and your neck will thank you for the super-soft cashmere. £250, Net-a-porter.com Photograph: guardian.co.uk

Join the queue In store next month is this gold Bex Rox stag head necklace. It looks more like a festive reindeer to us, making it the perfect nod to the festive season. Certainly more chic than a pair of jingle-bells musical socks. £188, Matches.co.uk Photograph: guardian.co.uk

Women’s buy of the week: A catwalk look at a fraction of the price – don’t say we’re not kind to you. This Oasis digital print shift dress with puff-sleeves and exposed zip at the back takes its direction from Erdem and Peter Pilotto, both red hot designers right now. Wear with over the knee boots and a chunky knit. £80, 01865 881986, oasis-stores.com Photograph: guardian.co.uk

Men’s buy of the week: There’s nothing nicer than seeing a flash of colour where it’s not expected. Slip this bright blue Topman cardie over your shirt and tie for a cheap, jaunty workwear update, plus it’s extra padding for the winter months ahead. £26, topman.com Photograph: guardian.co.uk
