Just bought this dress at the store and I would like to have your opinion if it's okay to wear it at my godson baptism ? I'm 18 weeks pregnant 🤰🏼 
Update: I forgot to mention that the baptism will be celebrated in my mom's garden. The priest comes at home so it's an outdoor baptism 😊. Thanks for your advices and comments
