Black Raveness Collar

Small pieces like this one decide whether a dark outfit looks finished. The Black Raveness Collar belongs to the Black Raveness Set, which also includes the Black Raveness Dress, the Black Raveness Sleeves and the Lina Heart Necklace. The wiki says it was added on 2025-10-18 in the Halloween 2025 update and obtained through the Halloween 2025 Quest, part of the Achievements collection.

In the data it is an Accessory with a Collar subcategory, wearable by any avatar, with toggles for variants. No price, code or VIP flag is listed.

For rounds, Gothic, Trad Goth and Corporate Goth could work, and Gothic Romance or Black Lace if you keep the rest of the outfit dark. Vampire Vogue is another option. Check your Closet first, as the quest belonged to the event.
