Posing for their annual Christmas card, the group of 11 got all dolled up, with the family's youngest in tow – baby Mason Dash Disick, who just turned 1 on Tuesday.
"Christmas cards have always been a REALLY big deal in my family," Khloé Kardashian, 26, wrote on her blog. "For as long as I can remember, my mom has made it a point to go all out. Whether it was a ninja turtles themed card, or bringing a Santa into the mix, each year she always managed to top the year before."
But Khloé says sister Kourtney and her beau Scott Disick's dapper-looking little one made this year's card just perfect.
"I'd have to say though that our card this year might be my favorite," Khloé writes. "It turned out beautifully – just SO glam! Plus, Mason is in it, which makes it even more special. Look at him standing there in his pinstripe suit."
