Fortuna chose this particular costume for another reason. On Ryloth, in many of its lower districts, Twi'lek women worked as prostitutes and performed in seedy strip clubs in the same cheap netting she now wore. By forcing her to wear it, Fortuna was showing Oola that like the women in these clubs, she was now a low cost Twi'lek whore that could be easily replaced if she was not obedient.
Jabba enjoyed enacting cruelty and humilation upon his slaves perhaps even more than the sexual pleasure he derived from them. The fall from grace and harsh irony that the costume represented for his new slave more than sated the hutt's tyrannical tendencies. The lovely views it offered of Oola's luscious body was an added bonus. It left little his eyes could not penetrate and even less when she danced, her costume shifting with each acrobatic movement. It left her assets unrestrained, transforming even her most desperate attempts for a chaste performance into lewd displays of bouncing green flesh. It made the Jabba's desire for her that much greater, leading to many pleasurable nights with his spirited dancer.
Bib Fortuna who seduced, manipulated, and had a lustful affair with the Twi'lek girl due to her naivety, immaturity, and impulsive personality, was the one who provided the netted costume (on orders from Jabba) in the first place.
To Oola, her costume was the first of many humiliation forced upon her within the walls of the palace. The moment it was presented, dangling from Fortuna's spindly claws, she realized how far she had been deceived and what her new life would entail. As she tearfully stripped for the mass of drooling monsters, revealing what no one save her family had ever seen, she knew she would never be covered and decent again. Even with the costume on, her body would always be bare, a simple glance revealing what she had guarded for so long. Even after being deprived of her last shred of clothing she dreaded putting the thing on, and when the netting was placed over her it was far worse than she could have imagined. It was several sizes too small, barely containing the curves her mother had given her, the straps strained and uncomfortable. She soon found that her movements, especially when she danced, created embarrassing malfunctions with her costume. By the end of her first week leashed to the Hutt, Oola not only looked like the slaves she had seen on her home planet but felt like one as well; an object, a trophy, a stripper, and a prostitute only good for giving pleasure to the creatures that owned her.
MangaEditIn the manga, the top half is stretched from her large breasts, leaving them to bounce around and her cleavage spread wide open. The stretched outfit is pulled from the body, in the style of a sling bikini.
This version of the outfit lacks the cloth that covers her pelvis that acts as her panties, completely exposing her crotch and anus so the whole court can watch her dance bottomless and relieve herself in front of Jabba and the court as she danced.
These features are only shown while dancing, and not while sitting where she can cover it up.
