So pretty! I love the rose gold on you. Didn't work for my skin tone, I had to buy the SS/YG. I was like you, debating 26mm or 31mm. In the end, I decided on the 26mm because it's classy and I can imagine myself still wearing it when I am much older. Besides, I think the two-tones with diamonds combo is rather bling, so prefer to keep it elegantly small. I'm plotting my second to be a 31mm SS/WG piece tho
