Reiss is on track for a 40% lift in sales in its current financial year, which ends on January 31.

Reiss finance director Steven Downes told the Telegraph that EBITDA from UK outlets would be around £12.7m, up from £9.1m in the previous financial year.

The figures came as Reiss revealed it would tomorrow reissue the Nanette dress worn by Kate Middleton for one of her official engagement photographs.

The white dress will be available in sizes 4 to 14 priced at £159.
