NWOT Women’s Large Deep V Backless Dress

Bought this summer 2022. I never wore this, and I don’t know why I did not send it back, but I didn’t. Too young for me to wear. Excellent condition. Very deep V and cute open back. Size large. Has three buttons at the back of the neck, the last picture shows it up close. I purposely left one unbuttoned but yes, they all three have closures. B-3
