Cute Gothic Lolita Nun Dress!

The white parts of the fabric are actually a lot more ivory/yellow-y than in the picture. It is not white though!

Bought from Aliexpress store called Himifashion. According to the page the dress measurements are:
Dress Length: 82 cm
Bust: 91 - 96 cm

I think the dress is supposed to be made of a thick cotton. It definitely doesn't feel wooly, but it feels like a thick and slightly stretch cotton of some sort. According to the page, it is supposed to be made of broad cloth?
I think the measurements are pretty accurate, my waist is about 29 in and my bust is about 36 in. The dress came down to above my knees and I'm 5'5".

I only tried on the dress, I've never worn it outside of my house. I think it is good quality, but I didn't like the look of ivory for contrast.
Comes with a black sash that it made of the same thick, stretchy material
