Natsuki vs Natsuki 2nd ver. vs Moe vs Moe 2nd ver.

Hello

 

I know that face-ups and clothing and wigs can make a sculpt appear different, but:

 

Are Natsuki & Natsuki 2nd version and Moe & Moe 2nd version all the same sculpt or are there slight differences between them?

 

I keep looking at all 4 and it appears they are the same sculpt but, of course, I may be wrong.

All the same.

 

If you look at the original release of Natsuki, her head is "Moe/ Natsuki Original Head" and the original release of Moe is also "Moe/ Natsuki Original Head."

 

Fun fact: Moe was the first girl to have an S bust.

Thank you, Cauldroness for your help and the fun fact
