Anyone do this or have a recommendation?

My dress is 12+ years old, never had it cleaned. My daughter (who is almost 10) tried it on for fun at my mom’s house (it’s been in a closet there) and it’s really in good shape except for some stains near the bottom and I’d like to get it cleaned. But my mom lives in a smaller town (across the country from us) so not sure about doing it locally. Any thoughts appreciated!
