Traumatized by a childhood incident where his love for traditional dolls was mocked, high school student Wakana Gojo has spent his adolescence as a social outcast, hiding his intense passion for Hina doll craftsmanship. He finds solace in the quiet of the school's home economics room, convinced that his world will never intersect with the popular crowd. However, his life changes in an instant when Marin Kitagawa, the class's beautiful and energetic trendsetter, catches him using a sewing machine after hours.
To Gojo's shock, Marin doesn't ridicule him; instead, she is mesmerized by his sewing skills. A dedicated otaku at heart, she reveals her own secret struggle: she desperately wants to cosplay as characters from her favorite video games and anime but possesses absolutely no talent for tailoring. She begs Gojo to become her costume maker, dragging the hesitant artisan out of his shell and into the colorful, complex, and often racy world of cosplay.
What begins as a reluctant agreement evolves into a transformative partnership for both. As Gojo applies his traditional techniques to intricate modern cosplay designs, he gains a newfound confidence and pride in his abilities. Meanwhile, the gap between the shy craftsman and the bubbly cosplayer begins to close, sparking a sweet and sizzling chemistry. My Dress-up Darling is a beautifully illustrated and touching story about embracing your passions, respecting the craft, and finding someone who loves the real you.
