This silk mini dress by Banana Republic Factory has a boat neckline. Long sleeves with functional button cuffs. Spaghetti tie at back neck. Drapey cowlneck feature at back. Unlined. Dress is new without tags. It’s never been worn. It’s beautiful but I decided on a different dress for the event I got this for. I included a picture from their website (in different color) so you can see how the back looks on.
