You're attired!

Tory boy style

Entrepreneur Raef Bjayou has hair that ticks not just one but three current fashion reference boxes: Merchant Ivory films, the Tory party, and Matt Damon as the Talented Mr Ripley. This is hair that means business. Photograph: BBC/Talkback

See also his swish matte suiting in on-trend grey, immaculately styled with matching tie and silk hanky combos. Jonathan Ross has described him as "something out of a Ralph Lauren catalogue". Last week, during a trip to Morocco, Raef was suitably horrified not to be in possession of his linen suit and this week we caught a glimpse of his posh velvet slippers: very Tom Ford.

The updated Carrie Bradshaw look

Lucinda Ledgerwood's job pre-Apprentice was as a risk manager; now, she is the one taking risks. Check out those Carrie Bradshaw homages: pink berets, quirky brooches, red leather gloves, floral frocks and even a short bob identical to the one Carrie had for a meeting at Vogue. No boring black suits for Ledgerwood. She is far more likely to turn up for work in a pillar-box-red coat or a bright green tailored jacket or a fuchsia-pink pashmina. Photograph: BBC/Talkback

This determination to up the quirk ante in the boardroom is an interesting approach in a contest based on not drawing any negative attention to yourself. When Lucinda is fired - we just can't imagine Sir Alan Sugar coping with her primary colours on a daily basis, so it's only a matter of time - we can't wait to see her exit suitcase. Our money is on her customising it with ribbons or an oversized corsage.

The silk scarf

A signature look of recently fired femme fatale Jenny Celerier, the silk scarf has become something of a style mascot on this series: bossy senior retail buyer Claire Young is also a fan. Sales manager Jenny kept viewers on the edge of their seats - would she plump for a fat cravat version or an air hostess homage? Meanwhile, Claire started off tightly winding hers around her neck, but the bossier she gets, the looser and more flamboyant the scarf, we notice. Photograph: BBC/Talkback

This week both Sara Dhada and Lucinda Ledgerwood opted for a tied-to-the-side look. These scarves do indeed add polish and sparkle to an outfit, and in a show where the only handbag action comes in the form of a black wheelie suitcase you drag off into the sunset, you have to give these women bonus points for pushing the accessories where they can.

Margaret Mountford's sunglasses

Candidates aside, Sir Alan's trusted aide, Margaret Mountford, a lady with neat silver hair and a fancy for pearls, long skirts and mother-of-the bride jackets, proved last week that it's not just her tongue that is sharp. During the Morocco task, Mountford wore a simply killer pair of sunglasses. Photograph: BBC/Talkback

Oversized and retro of frame, they prompted an immediate fashion-desk debate as to their origin. Alice Temperley or Linda Farrow Vintage? An email to the BBC met with a stony silence but never mind: the mystery of their origin only adds to their cachet. Bonus points this week for that oversized woven leather handbag, Margaret. Was it Bottega? Was it?

Yellow

Despite recent enthusiasm from fashion quarters, yellow remains a tricky colour - just ask Hillary Clinton. Last week, marketing consultant Jennifer Maguire chose to sport a satin blouse in Colman's English mustard yellow. This sheeny number had all the hallmarks of a vintage Karen Millen top you might have worn with jeans to a wine bar circa 1997. Even a waist-cinching belt, slash of red lipstick and a sharp haircut couldn't save the blouse - or her. She was fired. Photograph: BBC/Talkback

This week, the axe fell on international car trader Sara Dhada. Despite being sacked in monochrome, Sara had just weeks before sported a jaunty, canary-yellow jacket with three-quarter-length sleeves. At the time, we just liked how the jacket set off her trademark chandelier earrings, but with hindsight it was clearly the beginning of a yellow curse.
