You will never own too many Jeans. If I need to pick one outfit from my wardrobe my pick would be Jeans with a blazer. I think you can wear this combination for any occasion.
I prefer edgy Jeans with simple shirts. I found this special pair of Jeans in "7 For All Mankind". Oh yes, one think I forgot to mention; comfort zone... my Jeans have to be very comfortable. I don’t like it when I struggle in it.
Also I got this long denim skirt. It's new trendy but super easy to style. It will look good with any basic top.
