Altuzarra's white Christina blouse is an elegant lightweight piece that will take you from the boardroom to after-work drinks with ease. The silk-blend crepe is sleekly styled with a stand collar and long sleeves with feminine fluted cuffs that can be adjusted via a drawstring and finishes in a square step hem with slits at the sides. Tuck it into high-waisted trousers in the day switching to a sharp skirt and strappy heels later.
