Kstew's Secrets - What did a quick-fire beauty quiz with Kristen Stewart, face of the new Balenciaga Rosabotanica fragrance, reveal?
Preferred fragrance-dousing area: behind knees or décolletage?
"My go-to area is the boobs. I use two sprays, then I get dressed and spritz one on my clothes."
How much is too much fragrance?
"You definitely don't wait to walk into a room and blast everyone with your perfume."
What's the difference for you between Florabotanica and Rosabotanica?
"Florabotanica is for the morning - it smells like an early scent. And Rosabotanica is darker and a little muskier."
When did you last detox your make-up bag?
"Oh, that's a great thing to do. Things accumulate and get gross. I try to do it a lot. I'm always travelling, so I get the opportunity often. I'm super-OCD about getting rid of things I don't need."
What's the secret to your undone eyeliner?
"Usually it's a day old. Or you can just put it on and rub it your finger and a little spit."
Who would win an "eyebrow off" - you or Cara [Delevingne]?
"She has got me beat - her eyebrows are pretty epic. I'm glad to be associated with her in the brow department, through."
