the entire thing she was wearing is perfectly designed specifically to flatten the chest, that was it's purpose and it worked lol
breasts move and squish and position themselves to adhere to what they are placed in, just like they are not as flat as they appear in that top, they are also not as gigantic as they look in that red dress she has on in France 1-2 weeks ago
they are somewhere in between those sizes, and still very nice/big
