Bethany is a TM #62 head with dark brown eyes and TM #82's wig.
Olivia is a Nanea doll wearing a Monique "Doris" wig in black.
Since Jill and Silver are based on Elizabeth and me, we wanted to have our friends as part of the Islandshire group. The real life Bethany and Olivia are truly amazing artists, and you can check out a small portion of their work on their site here: https://www.oliviamoyart.com/little-sisters-home-page
