Calvin Klein strapless black dress

The definition of The Little Black Dress that does everything. Excellent condition, worn to several weddings. Sweetheart neck, side pockets (a deep love of mine). Technically it’s a 6 Petite, though I have no idea what that means in this context, because I’m 5’7” and never buy petite. I happened to find it on sale years ago, hence the anomaly size for me.
