The SubItems Collection of a ListViewItem will contain as many SubItems as you create and add to it: so, it's up to your code if every SubItem Collection has the same number of SubItems ... or not.

The other thing you need to be aware of is that the first Item in the SubItems Collection is always the Item the SubItems are being added to (whether you think of the ListViewItem that contains SubItems as a "parent," or just, usually, the first column entry: up to you).

Why the ListViewItem/SubItem structure was implemented this way: ask Microsoft :)

So, if you want to enumerate and clear only the SubItems, then your inner 'for loop should be: for(int i = 1; i < item.SubItems.Count; i++)
