This is definitely a spring/summer bag only, I think. It looks cute, but I think when you see it in person, the flower looks somewhat cheap, like the stitching, etc. isn't very well done.
And I don't think it necessarily has to be for someone in their 50s, I could see people in any age group pulling this one off. It's a very cute tote, and it's nice that there aren't any logos on it.
Anyway, that's just my opinion. I'd advise you to see it in person first and try it on (if you can find it anywhere, outlets, maybe?) before you get it.
