I find that as much as I like a glamorous kind of over the top outfit, sometimes the best outfits are really the ones that are simple and effortless. It's about going for basic pieces with an edge.
This outfit only has 3 pieces, each of which everyone should have in their closet: a black top, jeans, and black pointed toe heels. Since I already have a bunch of black tops and a few pairs of jeans I bought new versions of the things I already have just with different cuts and textures.
If you mix and match your basic pieces you may end up wearing your best outfit.
