The outfit only on my mind today since i came accross this clever sweatshirt bellow and the disco trousers: in classic tones of black and white + accessories in red color for contrast = one of the best/classic combinations...
Simple as that !
"I don't care" sweatshirt by iwantthatmusthave
"Disco" trousers in denim blue and/or black by dorothyperkins
White & silver pumps, and luminous bracelet by nastygal
...and for a color pop...
Red Zara bag
