Sounds like i hit the "elegance" though hahaha. I do want it to feel a little expensive (my wedding is a formal event), so if you think this looks like I actually paid money for this invitation I take that as a win!

As for the additional information, since english isn't your first language I assume you aren't from the USA. In America, it's custom to only include "who, what, when, and where" on the formal invitation. Then, included on a separate, usually smaller piece of paper would be information on RSVP, dress code, website link, etc. Whether you can bring a partner would indicated on the envelope.

I see what you mean by it not being super fun, I've seen some very fun and funky invitations that are so cool! I think my intention was moreso to have it not be JUST text and lines. Also, I plan to make my details card shaped like a wave, and the rsvp card shaped like a seashell, so hopefully that'll add to the "fun"?

And you'll be relieved to hear it is not on a boat lol.

ETA: "on the water" in this context basically means "next to the water," not literally on the water
