How to wear UGG boots?

Yesterday I bought these black UGG boots for 50 Danish Kroners = 9.05896 US Dollars. I bought them cause they are cheap (I am also sure they are fake, but whatever!) and I just wanted to try them out since everyone has them, I bought the cheap ones instead of the expensive ones, cause if I hadn’t liked them, then I would have just wasted my money :/
Anyway they are black and am really digging them <3
they look like this
So people I need help on how to wear them, I know the common look is with skinny jeans tucked inside UGGS *then I would add a cute top and a short sleeved cardigan, but I need more ideas. Also they didn’t come with any papers showing me how to take care of them or anything like that. When to wear them, in what weather, what time? and links and pictures would be very much appreciated.

Thanks in advance.
