Wedding dress or not, she looks beautiful, right?!
The stunning reality star is always making a splash, but it was her outfit (OK, as well as her fab figure) that had people talking as she stepped before the rest of her co-stars in this eye-popping white frock that boasted gold sequin detail along the skin-tight, plunging body and a tulle fishtail hem that fanned out at the bottom.
Of course, Kate's look garnered heaps of attention on Instagram (as usual, duh!) but many mentioned that the dress, which she nabbed from Wolf & Wake, FYI, would be much better suited to a wedding!
What do you reckon?
"OMG though this was a wedding dress! Something you're not telling us, Kate?" wrote one of her Insta-followers, while another commented, "WHAT a wedding dress."
One even said, "Definitely 100% a a wedding dress."
Kate - who looked nothing short of amazing in the sparkly number - eschewed a bridal-esque updo for cascading waves and she kept things nude and natural when it came to her make-up.
The star was joined by the likes of Georgia Kousoulou, Danielle Armstrong, Chloe Sims and Amber Dowding to name but a few - but it's safe to say she turned the most heads.
