Evening Invitations

Even though our day invitations are not yet finished, I've made a start on our evening invites.  I wanted to keep them as simple as possible.

I've carried over the purple swirls and created a document just shy of A5.  I shall print them out on the same ivory pearl paper as the day invitations and back them with a lilac pearl card.

What do you think? Also my next question is... Should I include a map and directions in with the evening invites?
