Nails!?

So I need some advice from anyone who can give it to me! I am going to be doing glue on nails for the wedding I'm going to; I also plan to put the stickers on them from Sally Hansen. What are some brands that are known to stay on a long time? What kind of glue should I use? Any other tips to keep my fake nails on longer?
If you have any ideas please post them as a comment!
