Based on the popular book series by Julia Quinn about each of the Bridgerton children: "The Duke and I" (2000, Daphne), "The Viscount Who Loved Me" (2000, Anthony), "An Offer From a Gentleman" (2001, Benedict), "Romancing Mister Bridgerton" (2002, Colin), "To Sir Phillip, With Love" (2003, Eloise), "When He Was Wicked" (2004, Francesca), "It's In His Kiss" (2005, Hyacinth) and "On the Way to the Wedding" (2006, Gregory).
The costume designers gave the two main ton families two very distinct color palettes. The Bridgertons typically wear pastels in shades of blue and pink, while the Featheringtons wear very bright colors and heavily patterned clothing that is often a shade of yellow or green.
Lady Whistledown, in the first chapter of the first novel, describes the Bridgertons as: "By far the most prolific family in the upper echelons of society. Such industriousness on the part of the viscountess and the late viscount is commendable, although one can find only banality in their choice of names of their children. Anthony, Benedict, Colin, Daphne, Eloise, Francesca, Gregory, and Hyacinth- orderliness is, of course, beneficial in all things, but one would think that intelligent parents would be able to keep their children straight without needing to alphabetize their names."
The costume department asked Jonathan Bailey to try different white shirts and sprayed him with water to find the perfect shirt for Anthony when he falls in the lake.
Jonathan Bailey shared that with intimacy coordinators, "no one goes into a [sex] scene quaking, worrying about how it will go - if you are concerned you can talk to them." And the actors are given an agreement to sign before each scene, "consenting to which bit of skin we are going to show in each scene and where we will be touched and how. It turns sex scenes into a choreographed dance."
