Halfpenny London SUN SLEEVES

Kate says:

"These spherical Mikado sleeves can be paired with any of our strapless dresses and tops. A wide strip of elastic is hidden at the top ensuring the voluminous sleeves stay in place. Fitted with a stretch Duchess satin lining, these sleeves gather beautifully and are a fabulous way to completely change the look of a simple dress."
