a fur vest looks absolutely posh and fab over any leather jacket, coat or outwear you have on. A denim or bicker jacket will also look great underneath a structured coat. Just make sure they are not bulky & they fit you well. Then you can mix and match pieces from different styles for a sophisticated look: silky top, hoodie, jeans/trousers, leather jacket. A sporty cap on, a cool bag, heels, lots of jewellery and a scarf will make you look like one of those off-duty models.
