This yellow Zimmermann Brightside Swing polka dot silk dress is cut with a round neck, three-quarter length peasant sleeves and falls to an asymmetric hem. It features a detachable belt at the waist and is fully lined. Catch us wearing this Zimmermann dress to our next wedding invite (no doubt we'll be the one during the disco to jump on the table and belt out Mr. Brightside). There's always one.
