This is a detachable collar from the authentic Lolita brand, Metamorphose temps de fille. The color is navy. It's a popular color, and I believe there weren't many made, making it a rare item that is no longer sold. It's an elegant detachable collar that is essential for classic Lolitas. It's a ribbon type, making it easy to use, and you can easily create an elegant coord by wearing it over a regular blouse♪ The lace is also lovely, as you would expect from a Lolita brand. You can coordinate it with classical blouses and skirts from brands like Baby, the Stars Shine Bright, Alice and the Pirates, Moi-même-Moitié, and Innocent World, or you can wear it with a JSK (jumperskirt) for a more glamorous look. This item is completely brand new. I purchased it online, so it hasn't been tried on by anyone, and there are no pets or smoking in the house. I haven't even taken it out of the bag, so I think the condition is good.
