No-one can forget Katie's Love Island entrance (remember that eye-wateringly tiny swimsuit? Oo-er!) so it was a total no brainer for her to turn her hand to lingerie design - it wouldn't be right to keep that body under wraps!
Like ex co-star Malin Andersson who also has her own fashion line, gorgeous Katie took to Instagram to lift the lid on her sparkling new drop and she looked absolutely sensational as she posed up a storm in a black lace triangle bikini with co-ordinating shorts to boot.
Katie captioned her snap - which has already racked up thousands and thousands of likes, "To all the women out there that like to feel sexy, check out my new range coming Thursday [18 August]. It includes some fierce lingerie [and] a cute lingerie nightwear set that I absolutely love. All stuff is designed by me and handmade in Britain."
The stunner - who recently defended pal Rachel Fenton against bodyshamers on Twitter - signed off with a really inspiring message: "I designed to empower all my independent sexy women out there," Katie wrote. "All shapes all sizes! Always be sassy!!!!!"
Of course, it wasn't long before the comments came flooding in, and it seems everyone is excited about Katie's new venture.
"Yassss girl! This picture is fire!" wrote one, while another Insta-user said, "You look stunning in this set! Congrats on the collection - gonna be a sellout."
Oh, you guys.
Katie follows in the footsteps of Love Island pal Jessica Hayes who is also launching her first ever collection with the online fashion hub.
Hands up if you can't wait to shop everything on Thursday?! Guilty.
