Urgent...Need Hairstyle

I'm doing a beauty pageant in August, however I need to take my professional pictures within the next week. I'm not sure what kind of extensions I should get. I think my hair is type 4a but I'm not positive. I want to keep my hair curly, so I need something that will blend in. Some kinds I've heard about are Bohyme and Halley's Curl. If you have any tips PLEASE let me know, I'm really in need of them

This is my hair in a twist out...it's a little frizzy but this is just a general idea of how my hair looks
