Pretty Green, the menswear retailer in which Oasis star Liam Gallagher is an investor, has posted a Christmas sales surge.

Pretty Green’s total sales including VAT climbed 39% in the six weeks to December 31, when like-for-likes advanced 33%.

The retailer reported that gross margins were “strong” in contrast to some fashion groups which suffered a margin hit following mild autumn weather.

Pretty Green’s international sales rose 12% and ecommerce sales, including VAT, were ahead by 41%.

Cumulative sales for the three months to December 31 rose 34%, or 27% like-for-like.

Pretty Green chief executive Richard Ralph said: “We are particularly pleased with our record performance over the Christmas period, but also for the whole first quarter of this financial year.

“We believe our results are testament to the strength of our brand both in the UK and Japan, where we already operate five stores.

During the first quarter Pretty Green opened two London stores and revealed the launch of six concessions in House of Fraser stores.

Ralph said: “We will continue to look to expand the brand during 2015, both in the UK and internationally, and remain very confident we will continue to deliver strong growth for the future.”
