Dress Help

So I had my baby girl 3 months ago, she's the light of my life. I've been going through some postpartum depression but that's another story. To cut to the chase, I need a little help in the self-esteem department, I want to look nice on Saturday night when we drive to Sydney & I go out for dinner with my husband for the first time

Question is: what sort of dress would look nice on me?
