Necklace not included. The sleeves are super cute! It's a long dress, perfect for pairing with short boots for events, dates, or lunch with friends ♡ I don't plan on losing weight, lol. If you'd like, I'll give it to you brand new (⁠ᗒ⁠ᗩ⁠ᗕ⁠) Hoping it goes to someone who will cherish it ♡ Please check my profile \⁠(⁠ϋ⁠)⁠/⁠♩.
