With rumours swirling that the superstar couple will be tying the knot as early as this weekend, Kim's keepin' it casual and cool as can be.

Do like the bride-to-be and pair your button-up with cropped jeans and pale pink pumps for ultimate effect. Next up from Kim: her Met Ball dress! Get. Ready.
