Earlier this year, she also generated headlines when she attended the Met Gala alongside Nicole, despite being 17 years old at the time.

The evening was especially notable as Nicole served as one of the gala's co-chairs.

"I definitely gained a lot of interest from those experiences and especially being privileged enough to experience them at a young age," she told Elle Australia.
© InstagramShe also praised her mother's influence, adding, "My mum is someone who has always been so creative and my biggest inspiration in life. She's a key part of everything I do."
In the same interview, Sunday explained that continuing her education has helped her maintain perspective while navigating life in the spotlight.
"The privilege of having these experiences and meeting so many new people is so amazing, but as a teenager, it's so easy to get sucked into all of it so fast," she said.
