I think Polly is very sweet, with a lovely, fresh yet vintage vibe. I do much prefer Molly or Holly though. Out of Polly and Poppy, I would absolutely choose Poppy, which I find to be a lovely name and the flowers are gorgeous too. Most people here hate Poppy with a passion though, which I have never understood.
