Curly Enough for a Curly Cut?

I am at the beginning of my journey to embrace my natural hair. I’m still very much in the experimental stage as far as figuring out what products work for and have been unable to make myself stop brushing my hair after the shower, but what I’d really like to do is get a curly cut so that I can really see what I’m working with.

My hair is thin/fine, frizzes easily, and fairly long. The salons near me say you have to have a minimum of 2B curls for a curly cut. Do I have that? I’ve never been able to tell.
