His Cinderella Bride: Harlequin comics

While managing a high-class rental boutique, Rose often dreams of her own wedding. Then, one day, she has an unexpected encounter. Included with a returned wedding dress is a planner that must have been forgotten. To return the planner to its rightful owner, she goes to a famous advertising firm and there she spots the man of her dreams; his name is Duncan Burke. As soon as she catches sight of him, he owns her heart, and then everything changes. It's obvious that many women desire him. To be with him, she abandons her previous image of jeans and flats, and dyes her hair blond, all to transform herself into a beautiful princess.
