This bra issue is silly. She’s a bit busty, and when a woman is running, jumping and whirling around, there’s going to be some bouncing boobs, no matter what bra she wears.
To think of all the points to be concerned with about Tlaib, foundation garments are not worth discussing.
I don't know, she knew she would be in public. Women think about what they'll be called upon to do when they get dressed. That's smart. The ones I know certainly think about "foundation garments." (Who wants to be embarrassed?)
What that boils down to is that T-lab is insane. I'd say she intended everything that happened, and everything you see--the most important part being, "Look-at-me-look-at-me-look-at-me!!!"
