How to wear a dress without a bra if I breastfeed?

Bárbara • I'm 28, and I have a beautiful baby girl born on May 30th, 2017 ^^ I also have a dog named Oliver and I love him lots!

Sorry if this seems like a stupid question but I have a event that I have to go and I breastfeed my 10 month old, I bought a dress and it has an open back so I don't know how to wear that without leaking! I don't really leak that much anymore but I know that after a couple hours without feeding my baby some drops start to come out! Any advice? Like is a bandaid helpful? O what could I wear instead of a bra? Sorry for my ignorance lol and thanks!
