Despite worries over an unseasonally mild autumn, the retailer bumped up profit guidance, pushing its shares almost 5% higher, also lifting fellow clothing giants Marks & Spencer and Primark owner Associated British Foods.
But the wider FTSE-100 Index trod water, closing up just three points at 6777.7, as attention focused on the US Federal Reserve's interest rates decision due last night.
Germany's Dax and France's Cac 40 closed in mildly negative territory.
Confidence has been underpinned by expectations that the US Federal Reserve will decide to maintain its current level of stimulus for the economy, resisting so-called tapering.

Next topped the risers board after it lifted profits guidance from a range of £635 million to £675m to a new bracket of £650m to £680m.
Sales in its third quarter to October 26 were up 4.3%, including another strong performance from its Next Directory online and catalogue business but also a 0.4% rise in retail stores, following a weather-hit first half dip of 0.9%. Shares rose 245p to 5450p.
Fellow high street chain Marks & Spencer rose 7.6p to 493.2p, ahead of its interim results due next week. Associated British Foods was also 26p firmer to 2222p.
Barclays also did well, despite a 26% fall in third-quarter profits and a warning to shareholders that it had been drawn into a worldwide investigation into alleged manipulation of currency rates. The group also said it had not increased its compensation provision for customers mis-sold payment protection insurance - unlike rival Lloyds Banking Group, which has had to top up funds set aside for PPI by £750 million to more than £8 billion.Shares climbed 2.4p to 268.5p
