The emote "⤜(-ヮ-)⤏" is a cute and playful emoticon that can be used to express various emotions such as happiness, excitement, or mischief. It does not have a specific meaning or context but can be used in any situation where a lighthearted and fun tone is appropriate. The phrase "My lovely Halloween costume" is not an emote but rather a statement about a costume someone may be wearing for Halloween. Without further context, it is difficult to provide a summary beyond this.
