This is a costume Skinsuit that Lumina has created for Alexandra to perfectly cosplay an extremely obscene version of Barbie. With Alexandra’s extreme proportions, even the perfect disguise cannot hide the impossibly giant breasts, miniscule waist, and huge butt.
With a perfect wig and a collection of extremely kitschy clothes, Alexandra becomes a perfect bimbo version of Barbie. Importantly, all of these clothes are created in a specific manner that makes it possible for them to be either locked or sewn onto Alexandra’s disguised body, ensuring that without Lumina’s explicit permission and help, she cannot remove any of them.
To make the act work even more, Lumina makes temporary changes to Alexandra’s mental state, behaviour, and personality, so she also acts as a kitschy, fashion obsessed Barbie.
