The sleeveless blazer is such a wardrobe staple. One of my favorite articles from the fashion Bible- Who What Wear is about ‘the third piece’, check it out here. Basically it just explains how to take your outfit to the next level by always wearing a 3rd piece. And this is that piece my friends! This culottes jumpsuit is basically a pj onesie it is so comfortable. In order to trick everyone that your onesie outfit is actually totally professional, slip on a sleeveless jacket. Viola! As I like to say, corporate chic.
