There was a whole thread earlier about wardrobe "malfunctions" and how various producers handle them without exploiting a model and maintaining their professionalism, so I know this won't happen by accident, BUT bikini 2 and bikini 4 look like they might fall off if the slime is thick enough.
Please do another human garbage disposal! This time use all industrial sized savory ingredients like mustard, ketchup, nacho cheese, and chocolate and vanilla pudding!
In order to make the proper decision, I think it would be best if you posted a backside view of all of the bikinis as well.
Honestly, it's Mallory. It don't matter which, it's going to be awesome. Plus, we know there are three other bikinis waiting to be part of an awesome shoot as well.
Love you, too
As long as Mallory finally gets slime poured inside the front and back of her bikini bottoms, then I honestly don't mind which bikini she wears for it
