Traditional way of proposing to my Costa Rican girlfriend. Advice please

I’m planning on proposing to my girlfriend but I want to do it the traditional way. I met her during the singles tour of Costa Rica with A Foreign Affair. We got along well during the socials and exchanged messages from my time there until now. While I was in Costa Rica, we got to hang out with each other, making me admire her more. Before I left, we both decided to make things official between us.

We've been together for over a year and half now. I could say that she's a really good wife material. She's caring and sweet. She's also concerned for my welfare which makes me feel special every time she asks how I am. Also, we share the same views on life which makes me confident that we will easily get along when we get married. Our compatibility can easily be seen in our conversations.

It's not everyday that I get to find someone like her. I don't want to lose her anymore so I'm planning on proposing to her soon. What I want to know is if there are any Costa Rican traditions that I need to follow before I pop the question.

She is the best thing that has happened to me and I want to spend the rest of my life with her. I want to prove to her that I'm willing to follow traditions if that's what it takes for her to marry me. I need suggestions and advice on what to do. Please help!
