Extensions for mixed hair?

Hi all! I am mixed 50% black and 50% white. My natural hair is very frizzy and I have been told that I have more fine hair. I am getting married in June and I need some extension for my hair. My hair is an auburn/copper color. It gets pretty blonde in the front and the red is extra highlighted outside in the sun. I don’t know much about extensions, so do you have any suggestions for extensions that blend well into mixed hair? My hair will be straightened. What should I do if I order some and the color is off?
