I got my glasses chain from an indie lolita brand called Poppemonica for about 1500 yen. They make jewelery and accessories and other cute items and lots of stuff with bunnies on it! They have a blog but it's not very active and is kind of lacking in pics. I picked up the glasses chain from a select shop in Osaka called Doris but they don't seem to have any left on the website. But I saw a ton of them at a recent lolita indies event I went to so I know they are still making them. They were pretty popular there actually. Here's a pic I found online of some past versions.
I'm sorry this isn't very helpful to people who want to buy one! But they don't look that difficult to make at home with a little bit of creativity ^^
Here's me and my glasses chain to help you see what it looks like on a real person. Full outfit (casual lolita) and up close.
So what do you think? Is it loli? Do you think it makes an outfit costumey? I've already kind of made up my mind personally that I like it but would you wear one?
