I don't know what other girls are like, and I don't know if the person who answers for others has experienced it personally.

Sports bra is useless to me anyway,

No matter what underwear you wear, you will shake violently when you run.

Especially the so-called sports style without rims, which swings extremely up and down,-pit,

I have been watched in the gym, and I have tried to run on my stomach in the deserted playground. It's really comfortable ~ ~

So I always wear ordinary underwear with rims when I run. If the belt is tightened a little and the chest is pressed a little tighter, it will be a little uncomfortable, but it will not sway so much.

Shock absorber, mobile comfort, enell, cw-x, Haitao, these brands are really not expensive, 300 can save your big breasts from sagging.
