I would have gone with some white jeans, black shoes and a tanned brown (if not slightly darker) jacket..because this gives you more variation in terms of colour &would look more fashionable :-)
black leggings+ white shirt
yes nice
You remind me of myself wearing all black LOL. You could try wearing a cardigan or a long necklace. I would recommend a scarf but it is not the proper season for that. You could take others advice and try swapping the shirt for something with a little more color. Otherwise recommend accessories with pop or a beanie.
I agree with Hannah, a pair of white tight skinny jeans would look good.
yes fine,, white shoes would have went, or white jeans and black shoes, but still nothing wrong with what you got on.
