We are Lutheran (Protestant) and, while our boys wore the traditional white, my mother-in-law made the gown and it's really girly. I almost had our 2nd wear a really cute sweater outfit my sister got him (my oldest was in the ER at the time, getting stitches; I was hoping "Oh, it's just too busy" would be enough to not have to change him...sigh...it wasn't) but he wound up in the girly outfit again. If we have a third, I might hold my ground more. Yes, it's symbolic, and if you go to a more formal church, you might want to check to make sure you're not offending anyone, but I know in my church it would not be a big deal at all. Even our pastors didn't baptize their children in white satiny gowns. :)
