I'm very conflicted about getting fake nails for the wedding. I have had them for 4 years but I got them taken off 1 1/2 months ago to save money. I know what they can do to your nails (my nails were soft and weak but with strengthening nail polish they got better in ~3wks. However, my normal nails are kinda meh, not very strong and break frequently (even before I ever had the fakes) so I'm worried about them all being the same length, or conversely, all being REALLY short for the wedding. I would get the fake nail material called pink (so that they are clear to look like natural nails). Also, I hate the Shellac stuff so I definitely won't be doing that.
Pros:
Look more uniform and nicer
Are much stronger - I can open cans and actually USE them for stuff
Can get them done a few days before the wedding and not worry about chipping (colored powder vs. nail polish)
Will last me all the way through the honeymoon
Once they're on, they're hassle free.
Cons:
Mess up your nails a bit
Take a little getting used to
Not as useful for somethings: I can't scratch myself as well (TMI i know, but since they're so thick they don't get itches too well)
Cost more money
Kind of hurt to take off
Takes more time to get on
