Mariana, originally from Bellassa, ran a bespoke tailoring business called Mariana's Exquisite Designs and Alterations. Her business existed during the final years of the Galactic Republic and the subsequent rise of the Galactic Empire. In the days of the Republic, her clientele consisted primarily of affluent residents of Ussa. Yet, following the Imperial occupation, she experienced financial difficulties and consented to accept sewing work from the Empire. This decision led to her estrangement from her Bellassan clientele, who consequently shunned her shop. Although the shop was typically deserted during the day, Mariana toiled through the night, diligently sewing and tailoring uniforms for the local Imperial garrison and the prison.
