Kourtney Kardashian could have taken cues from British conservative notions of dressing, but why would she? For a red carpet showdown inside London’s Berkeley Square Gardens Tuesday night, the 37-year-old mother of two dialed up her sex appeal and posed for the cameras in an oxblood-toned Julien Macdonald design that only a lady with a heck of a ton of confidence can rock.

Kardashian’s plunging dress dipped down all the way to her midriff and contained sheer cutouts along the waistline and hips. The sleeveless sequin frock hit just below the knee and though it could have easily taken an over-the-top turn, she kept it glamorous with slick locks and opted for a bold beauty look, which included a red lip. Gold-tinted satin sandals also complemented the standout ensemble.

Earlier this week, the reality TV star flaunted her love of lace in a black jumpsuit she paired with a lacey underlay and black ankle-strap sandals.

The eldest Kardashian star is seriously giving younger sister Kim a major run for her money.
