Personal style at work is not a frivolous pursuit or a feminine indulgence.  It's a way to boost our confidence and stay true to ourselves in a corporate environment that can often make us feel at best like a little cog in a giant wheel and at worst like an unworthy impostor.  Wearing outfits that reflect my personal taste and style is an outward way of demonstrating to myself and others that I am capable and can be successful just as I am.
