EXCLUSIVE AT NET-A-PORTER. Silvia Tcherassi is constantly pushing the limits of her signature statement sleeves - the designer underpinned the ones on this 'Barbara' blouse with layers of frothy organza inside to really hold their volume. Designed just for us, it's cut from soft silk crepe de chine and has an elegant drape. Pair yours with a playful skirt or wide-leg jeans.
