One of my girlfriends got the Nightcap Clothing Victorian Lace Dress in Black and it is just so pretty, and oh so sexy!! It features a lot of lace (so trendy) and a skin-baring open back. Ooh la la!
I have to agree though that this dress is quite short, but you know what? If you can pull it off, go for it. Alternatively, you can wear it as a tunic with black leggings or skinny jeans. You'll soon notice you're wearing it more than you thought you would, and you'll feel sexy every single time! What's not to like?
