There was one time during my busiest month when I went into school, and they were like, 'Sadie, where's your calculator? The PSAT is today.' I was like, 'The what?' Luckily, it was the practice one, but I still had to text my dad and get him to bring me my graphing calculator.
My stylist told me Chanel wanted to dress me for the 'Stranger Things' premiere. It was such a big deal for me, knowing that Chanel wanted to work with me and that I was gonna go to one of my first big red carpets wearing Chanel. That was such a huge moment for me.
Before, I would just only stick to a few certain colors that were considered good for my skin tone and good for my hair. But ever since 'Stranger Things,' the wardrobe people there, they would always stick me in these super bright colors. I discovered all these new colors that I just like wearing.
I think that's what's so fun about fashion: that I don't have to be defined by one particular style. It's whatever I'm feeling that day.
As much as I've always dreamed of going to college, I have to think about whether it is the right decision for me.
Comfort is number one for me with shoes. I like to do a test walk in heels to make sure I won't fall or get crazy blisters.
For the Emmys, my friend Rooney Mara designed a dress for me with her brand, Hiraeth. It's so neat to see a sketch turn into a full-on look.
