Meghan's monochrome ball gown worn to awards was so stunning we couldn't take our eyes off her

She was fashionably late for the awards – by two hours and fifteen minutes, to be precise – due to an issue with their flight from Tonga.

The Oscar de la Renta creation cost close to $13,000 but isn't available to the public. However, a similar dress can be purchased for $4,888.

Meghan paired her monochrome dress – complete with white tulle and a tweed laser cut bird design – with a pair of black stilettos.

Prince Harry wore a stylish suit and tie that matched Meghan's dress, and later that evening gave a speech about climate change and environmental damage.

He cited the bleaching of the Great Barrier Reef as an example of the destruction of our "most valuable resources." The prince added:

"It’s absolutely heartbreaking to see your natural treasures being changed forever."

The awards are Australia’s longest running awards for adventure and conservation, and Prince Harry has a personal connection to the prestigious event.

Back in 2013, Harry accompanied two Australian soldiers to the South Pole. Both soldiers later received the Spirit of Adventure Award.

Meghan has been making headlines with her elegant choice of outfits during the Australian Tour, and sales of the blue Martin Grant dress she wore in Tonga skyrocketed.

The Duchess seems to be quite fond of blue as this wasn't the first blue creation she was seen in recently. She also wore a navy dress by designer Dion Lee while in Melbourne.

While in Syndey, Meghan was spotted in a dark blue Stella McCartney dress and against wore a bright blue gown for her visit to Fiji.
