AP Celestial Cutsew OP (2016 release) sizing help?

Is the cutsew plus size friendly? I know that it is made out of jersey material that is stretchy but the question is...
How stretchy is it and will it fit a 41-43 inch bust? Is the sizing accurate to AP's own measurements? Any suggestions and information would be helpful! :)

Hello, everyone!

I apologize for using a super old account to do this, but I would really like your help! I am currently in talks with a Japanese company about creating a plus size gothic lolita clothing line, and I would love some feedback in the form of a survey to show them that there is a strong interest here for clothes like this. I also created the survey to give them an idea of what we'd like to see made and what the trends are. If you could help me out by taking a minute to fill out this 10 question survey and/or sharing it with any friends you have that fit the demographic, I would really, really appreciate it.

Here is the link to the survey: https://www.surveymonkey.com/s/2DBRSV7

EDIT: It's been brought to my attention via multiple sources that the pictures I've chosen (thoughtlessly) have caused much concern and unhappiness. So in order to avoid this, I'm switching all the surveys to a text version that will hopefully get me the answers I want without causing concern and upset. I do apologize for any offense or anger that my poorly chosen pictures caused. I am honestly very sorry, and I hope now the focus can be on the clothing and on my intentions rather than the pictures. Thank you for your feedback!

If this isn't an appropriate post for this community, I'm very sorry, and I'll take it down. Thank you so much for any help you can give me!

WTB plus sized cutsews, turtlenecks and high collar blouses

I want to buy cutsews, turtlenecks and high collar blouses that would fit bust 100-105cm and waist 90-95cm. Ordering from a seamstress would be an option, too.

Style should be Casual or Classic, like a t shirt with small peter pan collar or a long sleeved shirt with cuffs and top of a blouse inserted at neckline.
Colors should be black, dark brown, dark blue or wine.

I already checked taobao, but must shops seem to stop at bust 96 cm or I do not like the items.

I am also open to any shops or websites that you could recommend
