No, they aren't meant to hide anything. Still functionally shows everything but it's enough of a catch to make people want more.
And it doesn't blue-ball people so much that they never pay for her stuff again. To me it's the main differntiator between her and the rest of that verge agency core troupe (i.e. Kiki Passo, Sumner Stroh, Jessica Bartlett, and to a lesser extent Katy Jo Raelyn - kinda the middle ground of the group)
Someone like Kiki Passo is NEVER gonna show the goods, and I don't think Mikayla's gonna change her ways any time soon either cause well, it works - but hypothetically if her OF really started going cold and not bringing in enough money I seriously think she would reach a point where she'd say fuck it.
(Yes I realize the irony that half of her messages are captioned "I've never sent anything like this before but fuck it")
