Hedi Slimane continues to smash sales as creative director at Saint Laurent, as parent company Kering post official first quarter figures for the group. Now three years into his role at the creative helm of the heritage French brand, industry insiders were sceptical when he was first appointed, and with the brand's admirers showing their approval with their dollars, Slimane's critics will be retreating now. 

The Kering report shows that Saint Laurent sales are up 21 percent in the first three months of 2015 with particularly strong sales driven in North America (up 30 percent) with other territories also showing positive increases; Western Europe (29 percent rise) and Japan (up 22 percent.) 

The Kering group's overall total revenue has enjoyed an 11 percent rise this first quarter up to $2.9 billion. It is thought that some of this can be credited to favourable exchange rates and the sale of Movitex at the start of the year has helped to boost this figure. Without these revenue seems to be down by 0.6 percent overall. 

Joining Saint Laurent in a strong first quarter is Bottega Veneta with a 3 percent sales bump. Other sister companies such as Balenciaga, Stella McCartney and Alexander McQueen have had a 'solid' start to the year. 

Kering's usual front runner Gucci, is experiencing a time of change with the new appointment of CEO Marco Bizzarri and creative director Alessandro Michele, whose influence we can expect to see reflected in third quarter figures.
