An experienced knitter can make a christening gown like this one.
This is so cute for a party dress, that it almost makes me want to get better at knitting.

This is supposed to be a little easier to knit than the christening gown. If you consider yourself to be of at least intermediate skill, you can knit this for your precious little one.
Happy crafting,
