Dark Purple Cocktail Dress

Knee length cocktail dress, worn once to perform in a recital. Slightly angled like a halter/racer back, but not so much you can't wear a normal bra. Cups built in just in case. Jewel and draping embellishment on front. Labeled as 8P but I've never worn petite clothes in my life (5'7") and this hit just above the knee
