unos/unas/un/una with llevar/talking about clothes

Question

I am getting really confused and the books I read are saying different things.

After I wear (llevo), is there an article (un/una/una/unos) before the item of clothing. E.g. 1) I wear jeans = llevo vaqueros or llevo unos vaqueros

2) I wear a dress = llevo vestido or llevo un vestido

Does it have unos/unas if there is an adjective? E.g.

3) I wear black trousers = llevo pantalones negros or llevo unos pantalones negros

4) I wear a black skirt = llevo falda negra or llevo una falda negra

Does it have un/una/unos/unas if it is 'I am wearing' e.g.

5) I am wearing blue jeans = llevo vaqueros azules, no marrones or llevo unos vaqueros azules, no marrones.

What are the rules or can you just use both?

Gracias!

Answer 1

I use it like in english, but then again my spanish is not great, for Eg:

I'm wearing a dress = llevo un vestido

I'm wearing black trousers = llevo pantalones negros

I'm wearing some black trousers= llevo unos pantalones negros

ETC.

Answer 2

You tell me....

I am wearing jeans and blouse.

I am wearing a pair of jeans and a blouse.
