You have beautiful thick hair. Looks like a pretty strong wave that's getting more pronounced with length. Its got a classic beachy wave going, thats for sure. It looks too strong to me for 2a. But I have a hard time with this curl type stuff and don't think it's very useful. There are so many different wave patterns. When you add in density, condition, length, humidity, etc. it just gets silly. My hair seems to have a range, depending on all those things and I've been convinced at various times that my hair is straight, slightly waving, very curly....I guess the truth is, it's any or all of these, depending on the conditions at the time. I use more of a sliding scale rather than an exact type. You are for sure a strong wavy in that photo so 2 b is probably the best description, IMO.
2b/2c ( weather permitting - 3a), fine texture but lots of it, colored and highlights, BSL.
