Group Curses

What about curses tied to a specific group of women, or female friends?

What about Amy, Maddie, and Sara, who can't be within 100 feet of eachother anymore or their clothes will disappear?

Or what about the number of girls affected by a strange chain-text going around, that links every female together in its cursed conditions: they all must match what they are wearing at all times; if one girl is barefoot, others cannot wear shoes. If a girl is at the beach or pool, sadly the girls are all swimsuit bound. If one girl is nude, the others will find themselves naked wherever they are.

Or perhaps another group related curse?
