It's lovely, Scarlet. I would buy it and wear it in a heartbeat! I can easily understand its appeal.
But.
A couple of questions/considerations:
1. It looks quite different than most of the clothes I've seen you wear; dressier and more lady-like. That might simply be because I haven't seen all your clothes! But I'm wondering how it will fit with your overall wardrobe, not only in terms of colour but also style. I do think it would look great with jeans, so in that sense it's no problem. It seems versatile.
2. You mentioned that you don't tend to wear darker colours. This one would flatter you, I think, with your hair. So it's worth a try because it is quite versatile...can go with denim, black, blue, or maybe softer neutral bottoms like grey and taupe and olive or sage green. Or rust. Hmmm. LOTS of possibilities.
3. Collarless jackets can be a bit of a style challenge for some of us. If you have a long neck you might have this problem although your hair would mitigate it to some degree. I often find with a collarless jacket I am reaching for scarves to fill the gap, and not every top will work underneath it.
