Is she wearing a blue bikini under there?
I'm going with bikini because the straps are way too thin to be a monster bra.
And she would need a monster bra.
Back on the bikini theme.
Imagine Nancy re-enacting Pam Anderson scene from Baywatch running along the beach in super slow mo.
Actually replace running with Bouncing, Bulging, Busting out!
A few strides in and the bikini would be null and void!
Wow.
