Will vinegar get mildew smell out of t-shirts?

I bought a bra at the mall. Actually it was a bra set (2 bras) Anyways, they smelled like mildew so I thought I would just wash them. However, the smell is now on the t-shirts i washed with them. I returned the bras..... it was the malls fault. So, can I wash the tshirts in vinegar for the whole wash cycle? Will this help?
