I wore this dress as a bridesmaid in my sister's wedding several years ago, and sadly I haven't had occasion to wear it since. It looked great on all of the bridesmaid, even though we had extremely different builds (everything from short and petite to very tall and recently pregnant!). Here is info from the BHLDN website about it:
Full-skirted taffeta, ruched at the waist, bowed at the shoulders and topstitched at the hem. Falls to the knee. Back zip. Silk, cotton; acetate lining. Dry clean. Imported.
A Hitherto original, made exclusively for BHLDN Falls 23" from natural waist Also available in sunshine and powder blue
