I don't think most people realise that I largely work from home. I know that some of my fellow home-workers like to enjoy pjyamas, sweat pants and hoodies, but I don't tend to do 'casual' in the same way.
This for me is quite a casual outfit I guess. My hair is pretty messy (I've scrunch curled it with salt spray), and I've thrown a dress and cardigan on. I love stretch dresses for comfy days.
