This black SIR. Lucca cardigan midi dress is cut for a slim fit. It features a plunging neckline with a classic collar, all-over ribbed knit detail, front button-up fastening, long sleeves and an open hem.  Sharing a namesake with a title for a person from Lucania, an ancient area of southern Italy, we’re feeling very lucca-y to have found this SIR. dress.
