Quite a number of bra or similar top pics on OF the past month; you can always tell the difference by whether there is a seem or not. The one thing they have in common is the large gap that exposes a fair amount, perhaps 6", of sideboob closest to her arms. Since these bras are obviously custom made, I have to imagine that having this large opening is purposeful. If you have even watched a video where she is stretching the very tight material to encompass one boob and then the other, you know these are not some sort of slip on sports bras, but something intended to press her 50 pound boobs together and reduce their wobbling and pounding against each other when walking. And anyone who has seen OF videos knows that the straps, whether spaghetti or sports like, are very stretchy, offering no lift, but to keep the garment from riding down with the bounce that occurs with each step. Of course, with such stretchy straps and sideboobs extending perhaps 8" past her sides, there is a natural propensity for those straps to keep sliding off her shoulders every time she reaches forward, followed by the frequent stretching them back into place.
Just something I found interesting to watch as Beshine was explaining the reasons she wears bras when doesn't require the traditional lift. It also provides rationale on why she always takes off her bras when she is doing her food prep; not only because so much of it is done with her arms reaching forward and resting atop her boobs (hence straps slipping off repeatedly), but I have to imagine there is also a mess factor; I don't think I have a single kitchen food video where she is not having to wipe off her boobs at one point or more as things are either getting spilled on them or they bump into stuff. When your boobs stick out past your elbows, I guess that is to be expected.
