Note, with the pictures, they were taken at two different times of day. The color of the blouse is effectively more of a warm black in sunshine, but a blank none the less. :) 

I am unsure of the taobao brand this is from.

It is a free size crop-top blouse that can work for bittersweet/glothic coords. It has lovely lace and can be worn off the shoulder or on because of the elastic, so it is up to you. It is sheer, so I recommemd wearing it underneath a JSK or with something such as a slip underneath it so your skin isn't as noticeably visibile. 

I do speculate that individuals with larger bust sizes can pull this off no problem, but do note that it may hike up a bit.
