I ordered the Russian B, Russian C, and Russian D and I love them all. Russian B are a bit curled and a very nice look more geared for daytime or a more natural look. They are in the shorter side compared to my other types that I like to wear during the day, but the difference is they are a little bit curled which still makes them very pretty. Russian C and Russian D are very dramatic and look better on me for an evening look. They are very thick, and the curl is very dramatic and pretty. Because of all that, they are pretty heavy to wear but not uncomfortable. You just don't really forget you're wearing them. I love all these sets. No complaints.
