I can't find Black Lace panties or bra in the special event store. Help?

That's because they're not an event item. However, they are available for purchase already in the Lingerie Land department. Of course though, they're at full price.

That's because thier in the lingere shop already. They were created a long time ago.

What we have for the event now are re-colors I'd assume.

The above two posters are correct about both things. :)

These are recolors of those items. The black set is in the regular shops already.

Ah, thank you!
