Thank you.

strange, the outlook page is not the same.
Open the page in china version.
www.taobao.com
www.tmall.com

And fully load the page.

Just check by using other browser without login,
--> the page, is not under fully load mode. So will show the no stock option.
--> fully load the page, will remove the one no stock, so the page I looking at, is the one have stock  --- S1 DIVINA Pink（粉色）  / S2 DIVINA Pink（粉色）

Second item, better find other seller that have such option (Zowie EC2-B DIVINA), scare seller misunderstanding.

Third item, should be don't have problem because it is based on model you give to custom made.

The taobao system is like that, the one have no stock, website will not show the option or can not select the option.
The page after my side fully load it, just show these 2 pinks have stocks-- S1 DIVINA Pink（粉色） / S2 DIVINA Pink（粉色）

Second item, you google the answer or find other seller.
