LONG LASTING IMPRESSION. I develop a relationship with my couples so staying in touch is natural. I can't tell you how many have expressed that they "wished they added a charger". Small detail, big impact. You'll look back on those images for years to come, don't regret your savings.
The reason you can't decide on a single style for EVERYTHING is because you are utterly and completely YOU! Don't apologize, you have your OWN style. How wonderful is it to harness that!
Your event designer should revel in the fact that she gets to create something so distinctive. It's one thing to find a style and create an event, it's completely euphoric to create a style out of the things you LOVE.
