UPDATE- what are your thoughts on the dress for a baptism

We are baptizing my daughter this weekend and I'm not feeling any dress. I ordered this white one online but not sure if it's appropriate. What are your thoughts on it? Honest opinions. Does it look cheap? It's very see through as you can tell from my underwear🤦🏼‍♀️

UPDATE: thank you all for comments and opinions! I bought a half slip and wore it underneath. Pic is below. I also found this other dress but realized it has a stain on it. I could try to get it out. Which is better, white or the second one?
