Kind of overcreative today with the name of the post, right? It's because of the time difference and the tiredness, so you should forgive me. The only thing I'm able to suggest you now is to wear the most colorful coat you can find on top of the darkest shirt and jeans :) It's good sometimes to add something that big and that bright not only to the outfit but to the grey cold days as well. So keep experimenting and searching for something able to cheer you up in the weather like it is now in Baku.
Coat, slip-ons - Zara
Bag - A;ezander Wang Racketeer bag
