You talk to the clerk for a moment

"Yeah, I know what you mean..." Says the clerk, though a little confused and even more so as she sees the collar around your neck that doesn't go well together with the rest of your appearance at all. "Sometimes I go buy things just because I think they're cool, even though I'd never be able and wear them myself."

You notice she's pretty cute, though short and rather chubby to be a real looker, with big blue eyes in a round face and with spiky short hair dyed in black and stripes of blue. Currently she's eyeing the t-shirt you're about to buy like it's one of those things she'd really fancy for herself.

"True that." You agree while you pay up, then start wondering if you can get some help from this girl to remove the collar for you. "Umm... Do you think it would fit with this necklace? Like, for someone not built like me?"

"Uh, yeah... I guess..." She smiles while looking from the shirt to the collar and then back again. "And you're not going to try wearing it as well...?"

"No!" You smile back and shake your head. "Actually it was a total mistake trying this thing on, and now I can't get it off..."

"Awww!" She giggles, then motion for you to turn around and lower yourself so she can reach your neck. You can feel her look for a clasp or something but doesn't seem to find one. "Ummm... Actually, how did you get it on in the first place...?"

"I'm not sure really..." You mumble, now remembering that it can't just be taken off that easily. And it would be quite the risk to even hint at how this thing works to a complete stranger...
