I was initially terrified of jeggings. This didn't help much. But once I tried them, I never looked back. Now I have several pair (in fact, I may never wear normal jeans again). These are my current favorites.
Here's what you really came for:
Jeggings: J Brand Blouse: J Crew, also styled here Shoes: Tracy Reese (old, also love these) Sunnies: Top Shop (sold out, similar)
