If you don't find a place in your area, you may want to try looking online. I had a hard time finding a baptism outfit for my son that was reasonably priced, so I ended up buying his outfit online and got a good deal.
BTW--have you checked with Burlington Coat Factory? If there's one in your area, give them a call. They usually carry a large selection of baptism outfits and they are reasonable.
good luck,
