Whenever I'm doing something fancy (or if I'm in the mood) I go get acrylic nails. I would reccomend that you get them rounded, because that makes them look more real. Also, if they have it available, get the gel. It's just powder mixed in with this liquid stuff, but it also makes it look more real, and it helps it last longer. and I get a French everytime. So I'd reccomend that.
EDIT:
where I go to get mine done, they don't speak much english. Just enough to make some small talk and understand what I want done. and everytime it's flawless.
