Khloe Kardashian sizzled at beau French Montana’s 30th birthday in a $170 Vamp dress by Abyss by Abby:

Made from a premium stretch-jersey fabric, the dress has an open back with roping detail around the strap and waist. See it below in black.

Hot! Scandalous, but sometimes the occasion calls for that.
