The data also confirmed an ongoing national obsession with TV size, with sales of 60in to 69in screens up 145 per cent, and 46in-plus screens now the fastest growing area.
Fashion trends saw older customers opting for younger tastes, while the rise of more formal style among young buyers saw sales of of patterned square silk scarves rise 24 per cent, and pearls enjoy a renaissance with sales up 10 per cent.
Demand for gentlemanly attire increased, with bow ties up by 15 per cent, cravats by 10 per cent and brogues by 26 per cent, while a men’s dress cane and a white tuxedo jacket both sold out in eight weeks.
Meanwhile, coloured jeans, e-readers, three-piece suites and 3D TVs fell from favour.
