Sander Lak focuses on colors when looking through photos to inspire Sies Marjan's designs, which explains how he dreams up such kaleidoscopic collections. A lovely example is this dress, which is cut from teal satin that has a beautiful metallic sheen. It's ruched at the waist, creating a swishy asymmetric hem and has a high neck - complement it with swept-up hair and sparkly earrings.
