Classic black pants (Loft) could be worn pretty much every day in most people's world. Not that you should, I'm just saying...super versatile. Dawn is doing a fun ruffled top (Loft) (which is flattering on literally every body) and leather jacket (Express) with snakeskin shoes (DSW).
Monochromatic dressing can be very elegant. Keep shades as close to the same as possible when doing black on black. Over-accessorizing adds interest and presence to a monochromatic outfit.
Dawn's floaty button up (Express) is a bit oversize and trendy, yet matches her style because of what she is wearing with it.
