How can I make sure that my fake nails will stay on tomorrow?

So I want some fake nails for the start of school, which is tomorrow for me. But I know that I'm gonna be doing lots with my hands and I don't know if they will like, slow me down?


So how can I be sure that they won't?





Oh, also, should I get ';petite nails'; or ';really short nails';?





Thanks!!! :)How can I make sure that my fake nails will stay on tomorrow?
Go %26amp;%26amp; get it done at a salon. Belive me , those suckers dont come off even if you yank at them FOR AN HOUR straight ugh. Lol but theyre really pretty. Get gel =D
