OP it's easier than ever to look stylish. Clothes are so cheap now! And as a size 10
you'll have plenty of choice.
I'm a bit older than you (57) and I've got short, spikyish hair with lots of volume. Mine is fine with highlights.
I wear skinny jeans, tops and jackets, in bright colours. Sometimes I wear a longish cardi. I wear scarves and large jewellery, with a massive watch. I always, but always, wear makeup.
I think if you're quite petite with short hair, it's easy to disappear. So make every little inch of yourself count.
The only things I won't wear are bootcut jeans or trousers, anything flouncy, and round necked buttoned cardis. And some "smart" trousers can look frumpy imho.
I've recently got into brogues. Some of them are cool, especially on small feet (I never thought I"d be grateful for my little 3s).
Finallly, don't put yourself into a middle-aged style ghetto-wear what you like and do it with aplomb.
And yes, Pinterest etc is good for ideas.
