Hello ladies, so tomorrow my son is getting baptized in a Lutheran church. I got this dress because I thought it was very elegant and classy but I'm having second thoughts. I will be wearing a shape wear underwear underneath because I still have that kangaroo pouch and muffin tops, and also these really pretty nude heels. What do you guys think??
