My mother wouldn't let me have a theme for the wedding. I think I remember asking and she equated it to having a Bat Mitzvah. Lol. My Bat Mitzvah reception theme was The Secret Garden. It was in June, 1996. The Secret Garden or a garden party would be a perfect theme for a June wedding. My wedding is also in June, but I don't have a theme.
Don't feel obligated to have a theme Our June wedding theme is "wedding". lol
I feel like everyone goes nutssss with themes and it really causes the price tag (and sometimes the guest confusion) to go up, and IMO it's just not needed. Why not just be classy and classic? That being said, you can definitely throw elements of your style in there! Art deco is lovely.
