then and especially now is the skirt... - damals und besonderes heute ist der Rock... (Not sure whether to use ist or war, because I'm talking about past and present tense at the same time)
If you want to be grammatically correct, you need both: Damals war und heute ist der Rock.
Now, I know you don't need both verbs in the English version. What's that called? Is there a rule regarding it?
How about in German?
