Tan/brown is one of my favourite colours/shades I go towards. paired with a denim jeans and white its classic in my eyes. I paired it with the mustard sleeveless outerwear but I was actually looking for a beige/camel/sand coloured version but this was as well. If it was the beige version I would say a red lip but as it is mustard maybe nude, red or brown lipstick. I really like bags like the one shown either that or a clutch, the old school type chain bags.
Let me know your thoughts.
