Not every black-tie event is the same, so the rules may vary, but the important thing is always to respect the host and follow their vision for the nights dress code
The starlet, who some consider to be a sex symbol, said she wants to be far more than that
The long-sleeve, deep-V design has ruffled shoulders, an asymmetric high front slit and a front belt, with ruching that flatters and stretch fabric that moves with you
Whereas, the long sleeves is fully embellished with small 3d flowers and with black feathers also

Style it as a halter dress with a knot behind your neck, criss-cross the back, adjust the back length from midi to low, cinch it around the waist, or go for the classic wrap
