Next month I will unveiling both the new Garasaki and Aya. 「In Garasaki's case, I will unveil next weekend the new head, the body might not be ready yet]

So, Here's a couple measurement differences between Garasaki and Aya.

HAIR:

Garasaki will have slightly longer hair than Aya.

Aya's hair will be slightly on the wildside to reflect her dragonish look while Garasaki's will be more refined and elegant.

BREAST:

Garasaki will have a Japanese D cup, which is equivalent to an American C cup.

Aya will have a Japanese I cup, which is equivalent to an American G cup.

HIPS/BUTT:

Aya will have wide hips and a slightly large butt.

Garasaki's will be more subtle, the hips won't be as wide as Aya's nor will she have a butt as big as Aya's.

TAIL:

Aya will have a long and fluffy tail.

Comparing to the tail Garasaki has now, it will be slightly longer and more fluffy, also slightly raised.

To sum things up, Aya is meant to be the bombastic sexy figure. Garasaki is meant to strike a balance between cute and sexy, leaning more towards cute.

As for dresses, both of them will be able to wear dresses. Garasaki being the main one to wear dresses.

That's all I got for now. Any other questions you may have please write it down here!
