My dress isn’t appropriate for meeting his family

grace

So I have a dress and I have a tattoo on my back that is kind of inappropriate and his family at least to say don’t like inappropriate tattoos(old Italians). I meeting them for the first time and we will be all staying together for 3 days and I love the dress that I have but it’s only a little big around my chest area and I was wondering if I could take it up to a seamstress and see if they could hide in my back with. I’m already buying another dress that is classy and doesn’t show my back and a blouse. It’s been a long time since he’s seen his family and I’ve been with him for over 3 years.

the extra lace. Is that possible?
