I don't know why I expected this top to be a sweater, so I was a bit surprised when I received it. I suppose I should have read the details beforehand. Then again, I may not have purchased it if I had known, so I'm glad I didn't see that it wasn't a sweater. My usual size is a P/XS, so I ordered this in an XS. I also ordered this in an XXS because of the reviews. I'm keeping the XXS because it's just more form-fitting and figure-flattering. I usually don't like tops with polyester/elastane material because it shows every lump and bump, but for some reason, this top doesn't have that problem. Also, the neckline looks really pretty and unique, so this isn't your average black top. .I'm glad I purchased it.
