Ofuon Class orange v-neck 3/4 sleeve top sz 40

Brand: Ofuon Class. Occasion: Casual. Size (Women's): 40. Neckline: V-neck. Sleeve Length: 3/4 sleeve. Color: Orange. Pattern: Solid. Things to note: This is a Japanese brand by my research. The tag says size 40. I was not able to find a size chart saying what size that translates to. The fabric has a shimmer to it. I tried to post a picture of that in the pictures, but it doesn't capture it well. 0271
