finishing seams

[temptinglies.livejournal.com]

i'm sewing a wedding dress and i'm not sure how i should finish the seams. i don't have a serger so i was thinking that clean-edge finish (each raw edge turned under 1/4" and stitched) but i'm worried about the bulk of that. i could just zig-zag the raw edges but i want it to look nice since it is a wedding dress. i should also mention that none of these seams are actually visible unless someone decides to look at the construction of the dress, since there is lining and all. any advice?
