I have curls, and always look a bit " milkmaid " in anything pretty, so have come on to give you my edgy tips.
Leather is king
I have been very happy since biker jackets made a resurgence, they make everything more edgy. Leather trousers and skirts, ditto.
Footwear , never pretty or girly. Clumpy if it suits you, other wise pared down, or industrial.
Metallics can work, as can denim, but look at the cut, and avoid Next etc.
Pared down in general, so not much in the way of frill/ embellishments/ detail.
Statement jewellery, again plain.
And of course sometimes when I'm in the mood, I float around in a frilly white cotton dress looking completely milk maid, and loving it.
