Tuesday meetings? Coffee runs? An all white number says chic like no other. Just make sure you don't spill any of that coffee on yourself. Its classic simplicity is timeless for both in and out of the office.
Try finding a white blouse with an interesting silhouette or lining to make things pop. A matchy-matchy outfit can often feel bland, so make accessories as an extension of yourself. My watch, bracelets, and rings hardly leave my arms.
Shorts can feel too casual for work, but a tailored one may just pass with your boss.
