My 3mm wedding band arrived, but I'm not loving it

So I wanted to create a stack where each side is curved. I have half so far. But on our wedding day I'd prefer to have a plain platinum comfort fit band. The curved wedding band is 1.8mm, and the next one will be too. I love that my ering is 2.4mm and so I thought I'd like the 3mm band. But I didnt even when I wore it with just the ering or by itself. So now I'm wondering if I should try the 2.5mm or just skip down to 2mm. I think I'll give the 2.5mm a go since it'll almost be symmetrical and I'd like that. And I got the 3mm at Costco at a great price and they don't sell them in anything thinner. At least the return will be swift and ready.

Also, the bathroom lighting makes them look gold but they're all platinum.
