Black Lululemon Top

This is a black Lululemon top. It is size 4 and is in great condition. It also has removable padding and can be tied behind the neck. However, I’m unsure what type of top it is… I went onto lulufanatics to try and identify the item but could not find it. It potentially could be a swim top, but I can’t say for sure. On the mannequin it seems a bit longer, but I think it’s shorter than it looks.
