My son's baptism is coming up. I don't want to dress him in a white gown even though it is the traditional attire.

That being said everything is so expensive. I found a outfit I loved on etsy, but it is $80. (see link)

Does anyone have anything similar they want to sell used or know where to find a more affordable option. I was also hoping to avoid that silky satin looking fabric lots of the clothes for baptism come in.

He will be 5 months old, so looking for something that would fit in the 3-6 month size range.
