September is the casual month. Dont try to force yourself in a suit after vacations. Choose an outfit that you can easily go either to work or for an early drink. Go for a well tailored pair of pants, a comfy cardigan and of course a stylish pair of slippers. The ones that I am wearing are handcrafted straight from Mexico by Henry Bartones. Lastly dont forget to take with you a backpack that you can easily carry everything you will need.
