(Cover) - EN Star Style - Kourtney Kardashian has dressed up in an Alexander McQueen tuxedo for her family Christmas card photo.

The American reality television star poses in the sharp black suit, complete with a crisp white shirt from Dolce & Gabbana and Christian Louboutin stilettos for the festive shot, which will be sent round to all the Kardashians family and friends.

The 31-year-old, who found international fame on television show Keeping Up with the Kardashians, decided on the formal attire for her family picture so that she would match her boyfriend, Scott Disick, and their one-year-old son Mason, because she wanted to portray the three as a co-ordinated family unit.

I decided that I wanted to wear a suit since Mason and Scott were wearing suits. Do you guys like the look? she asked fans on her blog.

Never too young for high fashion, Kourtney dressed her son in a custom-made Astor & Black suit teamed with a designer Ralph Lauren shirt and shoes.

She revealed that she enlisted the help of her friend and celebrity make-up artist Joyce Bonelli and another pal Clyde to help her with her sleek hair and make-up, though.

Joyce did my make-up and we wanted to try a dark lip because it seemed to go with the mood of my outfit and the look, and Clyde did my hair, Kourtney revealed.

The picture was snapped by one of her favourite photographers, Nick Saglimbeni. (C) Cover Media
