The reason I'm going for such a small carat weight is because I would like to wear it with my watch and since I live such a casual lifestyle and spend most of my time inside or on the beach I thought this would be perfect, what do you think would be too much?
I don't think so at all, I think mine is right under 5 carats I believe and I wear it with anything, including my watch. And I have small wrists and I would have gone bigger if I realized I was going to trade in one of my bangles later on.
The thing that surprised me with the tennis bracelet is that it's really low maintenance in terms of styling. You kind of forget that it's on.
