Sports Bra and regular bra for workout?

[Help please.]

I was just wondering if I wore a sports bra to work out can I still wear a bra under or no? I just feel weird not wearing a regular bra? Help, anything?

i think that would be fine, haha. but its not that weird not having a regular bra on after a day or two. you just have to get used to it
