The model announced her engagement to boyfriend Joshua Kushner in July, sharing a photo of the happy couple vacationing in Italy.
Karlie has been the dating 33-year-old businessman, the brother of U.S. President Donald Trump's son-in-law Jared Kushner, since 2012, and looking forward to the big day, she hopes she looks as happy as the former "Suits" star did when she married Prince Harry in May.
"(Meghan) looked gorgeous on her wedding day," the 26-year-old gushed in an interview with Refinery 29. "I feel it's a day that you want to just feel happy, beautiful, and not stressed. I think what makes someone most beautiful, especially on their wedding day, is when that glow comes from the inside."
When it comes to the rest of her look, Karlie is planning to style her hair in an up-do "so you can dance and have a good time," and she will most likely go for a natural make-up look.
While the Adidas model admitted she's "still kind of enjoying the engagement bliss," Karlie is preparing for a busy few weeks now that Fashion Month has kicked off. However, she's already planned how she'll spend her time off once the spring 2019 presentations have concluded.
"When I have some time off, especially after a lot of travel, I really take the time to unplug and just completely ignore my devices," she explained. "I sleep in, read, eat nourishing and delicious food, and spend time with my loved ones. It's going into hibernation mode and really resetting."
