Lili Reinhart wore a textured olive-green triangle bikini top, crafted from a fine crinkled fabric that added dimension and depth to the muted earth tone (via Instagram). The halter neck top tied behind her back with thin strings. She paired the swimwear with high-waisted, medium-wash denim cutoff shorts with visible seam detailing.

The “Forbidden Fruits” actor wore her long honey blonde hair in waves with a middle part. She held a container of the Personal Day Overdew Barrier Cream Intensive Hydration Moisturizer in the first photo from the new campaign post. In the other photo, a swipe of the product was on her cheek.
