Hello! I believe you have to go to your design studio to design a custome! Travel to LAX, exit the gate, tap the bus icon, and choose "Bel Air", where you'll find your Bel Air Mansion. When you enter your home, you need to tap the first gold icon on the stairs and you'll be able to access your design studio.

If you're a bit later in the story line, she might be in a different room -- I can't quite recall off the top of my head!
