I made a WordPress theme for escorts! Unlike other themes which cater to multiple uses, this is designed specifically with escort websites in mind, so it is very lightweight at 322kB. (In comparison, even basic WordPress themes like Twenty Twenty are over 1.5MB.)
Escort One features full width header with background image, menu bar that changes colors when scrolled down to maintain legibility, toggle menu for mobile, and a widget area in the footer.
It is MIT licensed, so if you want to modify the theme, you can edit it however you like!
