NWOT Derek Lam 10 Crosby Robertson High Waisted Crop Flare Pants These still retail for full price in all major high end department stores. MSRP $365. They came to me straight from Saks and they took the tags off to prevent customers from returning. But these are new without tags. Derek Lam 10 Crosby stretch trousers, featuring sailor button detail. Fitted with flare legs. Hem cropped above ankle. Hook-eye/zip front; belt loops. Cotton/spandex. Imported.
