Cocktail_dress

The definition of cocktail dress seems to be quite vague: kind of formal (but not always), sometimes long, sometimes short, strapless or not...

Should we nuke the tag?

I'd rather we try to pin down a solid definition than nuke it. We don't really have any good tags for semi-formal dresses. We just have formal dress, but that's so vague and all-encompassing that it's hard to find anything specific.
