Hi, and welcome to Basenotes!
I'm at a bit of a loss here re: whether aquatic-type fragrances are suitable for formal wear. I would be inclined to say that they are, but I'm sure some of the more experienced members here could give you a better bit of advice about this.
To carry on:
I could list many aquatic fragrances here. I will keep it to one or two. I noticed that someone (in a recent thread) listed
Pasha de Cartier
I really like Pasha a lot. It's a real "classy" fragrance IMO. Another one I really like as well is
Kenneth Cole New York
Your list looks good. The AdG is obviously a big favorite. The Acqua di Parma Blue Mediterraneo Fico di Amalfi is a very nice Fig scent. I also love Un Jardin En Mediterranee by Hermes for a great Fig scent.
