- Sienna’s look: high-waisted straight-leg jeans with a crisp white tank, soft makeup, and undone hair.
- Oli’s look: relaxed mid-wash denim shirt paired with matching jeans and subtle sneakers.
- Their chemistry: nothing about it felt over-styled—just confident, cohesive, and genuine.
That combination of simplicity and connection is what elevated them from stylish individuals to a unified fashion force.
