I have written a post here earlier, describing how leggings are new jeans of today. There are ample number of ways in which, you can team them up and create different looks.
You can wear your leggings the traditional Indian way- what is called suit. You may or may not wear a duppatta (scarf) to finish your look.
You can wear it with a skirt. Leggings are not pants. They look cute when they are paired with a skirt. Wear them with boots if it is a straight skirt. This look can be worked both as a casual day time look as well as when you are going out at night.
Sport leggings with a tunic top. Throw in a scarf to finish your look.
Here is the Indian version of a tunic top, called Kurti.
Just like a skirt, you can wear your leggings with a dress and convert all your summer dresses to be worn in winters.
Here are examples of different kinds of dresses, you can wear your leggings with.
You can also wear your leggings with long coats. Boots will be mandatory to finish the look.
You can also wear your leggings with long woolen sweater.
Exhibit your tights with a nice, long, sequined top.
Don it with a flouncy skirt.
Wear it with smart, short jacket.
Go colors or patterns with your dresses.
Leggings can also be worn while exercising.
Wear them with long tops. To accessorize, add a belt.
You can even sport them with T's.- short or long.
With a kimono
Last but not the least, you can wear leggings/ jeggings any which way you like. They are really versatile.
