Bought this from Shein and was planning to return it, but I missed the deadline. Never been worn except to try on. As far as I can tell there is no tag to tell front from the back, so I think you can wear it either way. There's also no tag that says the size, but it is most likely a small. There is an inner layer of fabric around the top of the tank. I tried to capture it in the photos (last two).
