I think it's fine quite like it.
I probably wouldn't wear it (too short and curvy) but my colleague who is 50 I think and who is a very funky dresser would wear it with boots thick tights, dark jacket and tee. People tend to admire her style - she does not look like mutton dressed as lamb.
Hate ballet pumps though. To me they do look like should be worn by little girls/teens.
I think I possibly dress in a more edgier way since I split with H who was rather conventional in his outlook. In fact i have just been looking at old photos and saw one of me at my brothers wedding in a really frumpy Jaeger dress and hat. I was 34 going on 50!! Never wear a suit anymore either.
I tend to wear jeans (boyfriend or bootleg)/linen/crops mostly with longer cardigans/tunics or tee shirts and boots. Aim for an urban style. And sometimes knee length skirts with boots and a long sleeved T.
Occasionally wrap around dresses but I feel really quite frumpy in these.
Denim jacket, leather jacket, parka occasionally smart mac/coat.
Not so keen on he twee look. Mutton dressed as lamb to me is a more formal look. Designer clothes with heels and lots of slap.
