Place ladyfinger biscuits on a rimmed baking sheet and drizzle with dessert wine; let stand 5 minutes. In a large bowl, whisk heavy cream with confectioners' sugar until soft peaks form.
Place 5 soaked ladyfingers in a 2-quart serving bowl. Top with 1/3 cup lemon or raspberry curd, then half the whipped cream. Top with remaining ladyfingers, 1/3 cup curd, and remaining whipped cream; top with remaining 1/3 cup curd. Refrigerate 3 hours (or up to overnight) before serving.
