I think the best way to make a long tulle skirt wearable, is to choose sneakers instead of high heels. So you become less a princess and more a modern woman, which is not so bad!
There is no rule stating that you can only wear high top sneakers to the grocery store or a walk in the woods; you can even opt to wear them with a dress (long and short), cropped pants, elegant suits and, of course, jeans.
Among all the different current styles, what I like best is Boho mixed with normal everyday clothes. Another trend I'm all about has got to be lace, because I find it so feminine and romantic and I believe we generally don't wear it enough.
