More eyes are set to be on Twiggy since her heyday in the 60s as the recovery hopes of Marks and Spencer are put to the test this week.
The high street giant is using the supermodel as the face of its major pre-Chistmas campaign - and it's among a clutch or retailers, including WH Smith, which are hoping to prove they have the right strategy to overcome the current slowdown.
Broker upgrades have fuelled optimism surrounding Marks & Spencer in recent weeks, although this will come crashing down on Tuesday if evidence from the second quarter fails to point to a bottoming out in its sales decline.
It should be the biggest test yet for chief executive Stuart Rose, as autumn ranges will reflect his ideas rather than the designs of previous management.
While tough trading conditions will cloud the outcome, any suggestion that the worst may be over for the retailer is likely to reinforce views in the City that M&S is worth the 400p a share that Bhs owner Philip Green was willing to pay last year before he abandoned his £9.1 billion takeover campaign.
At its last update, M&S said like-for-like sales fell 5.4 per cent in the 14 weeks to July 9, with the biggest falls in clothing and homewares.
At WH Smith, chief executive Kate Swann will look to buy more time for the retailer's recovery strategy when she presents annual results to analysts and investors on Thursday.
Profits of around £71 million are expected for the year to August 31, up from losses of £135 million a year earlier after intense competition from supermarkets exposed the failings and lack of focus at the group.
Under Ms Swann, the group has launched a threeyear plan to drive cost savings of £30 million and concentrate on the parts of the business that shoppers look for WH Smith to be strong in, such as greeting cards and books.
So far so good for WH Smith, but analysts will be anxious to learn how the company intends to lure in Christmas shoppers at a time when trading conditions are seen as being the toughest in two decades.
Moss Bros will take another step in its recovery on Wednesday when it unveils half-year profits of at least £ 1 . 4 million, up from £700,000 a year earlier.
Improved product ranges and supply chain changes have boosted Moss, which is now on course for full-year profits of £7.6 million, against the £5.5 million seen a year earlier.
Sportswear chain JJB Sports is expected to show a sharp fall in interim profits when it updates the City after suffering what it has described as the toughest trading conditions in memory.
A vicious price-war among operators in the sector recently claimed the scalp of operator Allsports, while rival JD Sports warned trading had been disappointing since the end of July 30.
So, at the end of the week, we may all all be in a better position to judge how some of our bigger high street names are positioned prior to the big festive season battle. I wonder if Twiggy will be celebrating?
