Bras are different, you're supposed to wash them every 2-3 uses because they are not as directly exposed to bodily fluids and are typically made of more fragile material and will wear out quickly if washed too much. 

But never washing them?? That's disgusting!

Lol, yeah, totally different to underwear bottoms. I do wash mine every time, but I wear crop top bras everyday these days cause they are more comfortable. So not the same as underwire. 

This women never washed them… EVER! 

The worst part was the amount of other women agreeing with her!🤢
