What you wear to a christening is entirely a personal choice. However, it’s understandable that you will want to make a good impression and fit in with the social expectations of the occasion. You might be wondering whether a hat is a good idea for a christening, in much the same way as you might wear a hat or a fascinator at a wedding. It’s not as clear cut as that, unfortunately. Many people will wear jeans and a pretty top, whilst others will wear formal clothing that is more befitting of a wedding.
If you are unsure, check with others what they are going to be wearing so you won’t feel out of place on the day. However, if you are happy with what you are wearing, then that is the most important thing. Wear a hat if this makes you feel comfortable, and if not, save it for the next wedding you attend.
