There are 10 essential neutral pieces you need for the core or the base of your professional capsule wardrobe, and all of them can be found in this blog post.  They're all classic neutrals that are simple enough to be worn for several years.  They include, a basic black blazer, a white button-down, a black classic pump, a black and white striped shirt, black flats, a blouse, a black sheath dress, a black pencil skirt, black trousers, and a black handbag.

In this blog post, I document my second experience doing the Winter 10x10 Wardrobe Challenge.  Only 10 pieces of clothing, creating 10 outfits, for 10 days.
