How Old Are the Characters in "Bridgerton"? Let's Investigate

Kate's younger sister, Edwina Sharma (Charithra Chandran), is probably about 17, the age at which she would first be eligible to make her debut. Edwina is 17 in the "Bridgerton" book that inspired the second season, and while it's likely that she's the same in the show, it's possible Netflix adjusted her age, as they did Kate's. Kate is younger in the book — around 21 — which would make Edwina about 22 years old if their age gap remained consistent.
