Kourtney, 37, kept things (sort of) business proper in her high-waisted wide-legged trousers and matching blazer.

She turned the sexiness on full blast by adding a lingerie-like bralette that made her chest the focal point of the outfit.

With neutral, sultry makeup and glistening straight locks, the reality TV personality looked absolutely stunning for the event. Kourtney chose a pair of tan sandals for her small feet.

Unfortunately, her footwear is barely visible beneath her long trousers. Any guesses as to the designer behind this pair of toe-strapped sandals?
