Theres no way she’ll be able to find one that fits her, especially in the US, that isn’t custom made; I don’t think I’ve ever seen Tessa or Leanne in a correctly fitting bra either.
I think for big boob models like Tessa and Leanne that have some experience, that is a matter of choice. It is just a simple fact/trick that big boobs look hotter in certain angles and certain poses when in bras that are too small.
Yungfreckz being an amateur seems like her bras are *way* too small and she's bulging out from the sides, top and we are getting mainly only her Instagram style angles for the most part. She looks like about an M cup to me which shouldn't be that hard to find if she really wanted it.
