White Ribbed Body with High Neck and Chain Strap/Back (Black/Silver/Gunmetal colour) 

The material is thick and stretchy, it is not a cheap jersey fabric and it isn't see through. There is also a lining fabric so it can be worn without a bra.

Brand is Missguided, bought from ASOS

There are some small makeup marks on the back of it which is why I couldn't return it. I'm sure this will wash out but I haven't washed it to keep the tag on and show it is new. I have shown the marks in the last photo.
